The middle 68% of a normal distribution is also known as one standard deviation away from the mean in both directions. This means that approximately 34% of the data lies on either side of the mean within this range. To determine which z-score is NOT outside the middle 68% of the data, we need to find the range of z-scores that fall within one standard deviation from the mean.
Using a standard normal distribution table, we can find that the z-score corresponding to the 34th percentile is approximately -0.44. Adding and subtracting this value from the mean of zero gives us a range of approximately -0.44 to 0.44 for z-scores within one standard deviation from the mean.
Looking at the options provided, we can see that (c) 1.8 and (b) 3.8 are clearly outside of this range, while (a) -2.8 is also outside. Therefore, the z-score that is NOT outside the middle 68% of the data is (d) -0.8, since it falls within the range of -0.44 to 0.44.

They compensate by developing an increased sensitivity to taste (gustation). They often become depressed. 1 point The different taste qualities (sweet, sour, bitter, salt, umami) each have their own area of the tongue that is most sensitive to them. True False
The statement that The different taste qualities (sweet, sour, bitter, salt, umami) each have their own area of the tongue that is most sensitive to them is False.
Gate Theory states that competing signals such as rubbing your elbow can make you more sensitive to pain. This theory suggests that physical signals such as massage, pressure, heat, or cold can block the transmission of pain messages through the spinal cord and prevent them from reaching the brain. Therefore, when people rub their elbows or apply pressure to the area, this stimulates the non-painful touch fibers and decreases the transmission of the painful stimuli.
As per the statement, patients who are allowed to self-administer morphine use less than when they receive injections from healthcare providers is True. Olfaction is a very important sense for humans, and they often become depressed when they lose their sense of smell (olfaction). The statement that The different taste qualities (sweet, sour, bitter, salt, umami) each have their own area of the tongue that is most sensitive to them is False.

in an automobile, if the center of mass is low, the vehicle will tend to flip when going around a corner. (True or False)
The statement "in an automobile, if the center of mass is low, the vehicle will tend to flip when going around a corner" is false.
This is because if the center of mass (COM) of an automobile is low, it will have a low center of gravity (COG), which will increase its stability and reduce the tendency of the vehicle to flip over.
The stability of a vehicle is influenced by its center of gravity.
The center of gravity is the point at which the mass of the vehicle can be assumed to be concentrated.
The car will tip over if the force exerted by the turn is greater than the force exerted by gravity when the vehicle's center of gravity is above the wheels.
If the center of gravity is low, the car will be more stable and less likely to flip over.
In contrast, a car with a high center of gravity will be more inclined to tip over.
The height of the vehicle's center of gravity can be influenced by the distribution of mass.
The heavier the mass is, the lower the center of gravity will be.
Furthermore, when the vehicle is in motion, the weight distribution varies.

A sample of blue gray soilwas obtained from Paine Field in Everett, WA to determine its Atterberg Limits and classify itssoil type according to the Unified Soil Classification system.84% of the sample passed through the #200 sieve with 16% retained on the #4 sieve. For one of the PL determinations, the wet weight + dish = 11.53 grams and the dry weight + dish = 10.49 grams. The dish only weighed 4.15 grams. Compute the plastic limit. Three determinations of the liquid limit were made. For 17 blows, the water content was 49.8%; for 26 blows, the water content was 47.5%; and for 36 blows, the water content was 46.3%.
Required:
Evaluate the soil type, indicate the information on a plasticity chart,and give the Unified Soil Classification System (USCS) symboland the proper narrative description.
Solution :
1. PL \($= \frac{11.53 - 10.49}{10.49 - 4.5} \times 100$\)
= 17.36 %
2. Liquid limit at 25 number of blows,
\($LL = \frac{(26-25)\times 49.8 + (25 - 2.17) \times 47.5}{26-17}$\)
\($= 47.75 $\) %
Since 84 % of the passes the number 200 sieve the soil is immediately fine grained and MI, OI or CI because LL = 47.75 % > 35%
Therefore, the Plasticity index, PI \($=47.75 - 17.36 = 30.39$\) %

Technician A says that the computer can be used to control the output of the alternator by controlling the field current. Technician B says that voltage regulators control the alternator output by controlling the field current through the rotor. Which technician is correct
The voltage regulators control the alternator output by controlling the field current through the rotor, so Technician B is correct.
Voltage regulators control the alternator output by regulating the field current through the rotor. The voltage regulator is an integral part of the alternator system and is responsible for monitoring the electrical output of the alternator and adjusting the field current to maintain a stable voltage.
The voltage regulator continuously monitors the electrical system's voltage and sends a signal to the alternator to adjust the field current accordingly. If the voltage drops below the desired level, the regulator increases the field current, which boosts the alternator's output. Conversely, if the voltage rises above the desired level, the regulator decreases the field current to reduce the alternator's output.
While computers and electronic control systems are used in modern vehicles to monitor and control various aspects of the electrical system, such as engine performance and emissions, they do not directly control the output of the alternator by manipulating the field current. The voltage regulator is responsible for that task.

Air flows through a pipe at a rate of 200 L/s. The pipe consists of two sections of diameters 20 cm and 10 cm with a smooth reducing section that connects them. The pressure difference between the two pipe sections is measured by a water manometer. Neglecting frictional effects, if the inlet temperature of air is at 25oC, due to the compression of the air at neck of the pipe contraction, the outlet temperature is measured at 30oC, determine the differential height of water between the two pipe sections. Take the air density at 25oC and 35oC as 1.20 kg/m3 and 1.19 kg/m3 respectively.
The differential height between the two pipe sections is 0.05m
What is Differential HeightThe differential height of water between the two pipe sections can be calculated using the following equation:
h = (Q²*(ρ₂-ρ₁)/(A*g)) * (P₂-P₁)
where
h = differential height of water (m)
Q = volumetric flow rate (L/s)
ρ = density of air (kg/m3)
A = cross sectional area of pipe (m2)
g = gravitational acceleration (9.81 m/s2)
P = pressure (Pa)
Substituting the given values in the equation we get,
h = (200*(1.19-1.20)/(π*(0.1)2*9.81)) * (30-25)
h = 0.05 m
Hence, the differential height of water between the two pipe sections is 0.05 m.

If the oil pressure gauge fluctuates over a wide range from zero to normal operating pressure, the most likely cause is air lock in the scavenge pump intake.
Oil pressure gauge fluctuation is a common problem for the engine. It can occur due to various reasons such as faulty oil pressure gauge, oil pump failure, improper maintenance of the engine, oil leakage, and much more. But if the oil pressure gauge fluctuates over a wide range from zero to normal operating pressure, the most likely cause is air lock in the scavenge pump intake.The scavenge pump in the engine is used to remove the oil from the engine's crankcase and delivers it back to the oil tank. If there is an air lock in the scavenge pump intake, then it will not pump the oil properly from the crankcase and deliver it back to the oil tank. It will cause the oil pressure to fluctuate over a wide range from zero to normal operating pressure.To fix this issue, you should first check the oil level in the engine and make sure that it is at the proper level. After that, you can check the scavenge pump intake for any air lock or blockage. If there is an air lock, then you need to remove it. If there is a blockage, then you need to remove the blockage to get the oil pump working again properly.

(a) H2xWe know,H = B/μFor region 1,μ = μo
Hence, H1 = B/μo........(1)
'For region 2, μ = 240
Hence, H2 = B/240........(2)Given, H2x = -5A/m
From equations (1) and (2),
B = μo H1 = 10 x 10^(-6) x (10 åxtảy + 12ảz) Wbm^(-2)
B = 10^(-5) (10 åxtảy + 12ảz) T
For region 2,B = 240 H2 = 240 x (-5) x 10^(-7) x ẤxB = -0.012T
From equation (2),
Hence, H1x = H2x + M(x)
Now, B = μH= μ(x) H = μoH1 for x > 0 and B = μH= 240 H2 for x < 0
Now, M(x) = Ř(x)/2and Ř(x) = M(x) x 2
Since, the two media are identical, we can apply the boundary condition given by,
H1n1 - H2n2 = Ks
Thus, H1x = H2x + M(x)
On the interface, x = 0,H1x = H2x
Hence, H2x = H1x - M(x)
Putting the values, we get H2x = 3A/m
(b) Surface current density, R
We know, Ř = Kt x H1n1
Using the above equation, we can determine the surface current density Ř.
Now, we know that H1x = H2x + M(x)
Thus, H1n1 = H1x and H2n2 = H2x
So, H1n1 - H2n2 = Ks => Ks = M(0) = 0
Hence, Kt = μoWe know that H1n1 = H1
xHence, Ř = Kt x H1n1= μoH1x
Now, we know
H1x = 3 A/m
μo = 4π x 10^(-7) H/m

A student lives in an apartment with a floor area of 60 m2 and ceiling height of 1.8 m. The apartment has a fresh (outdoor) air exchange rate of 0.5/hr. The stove in the apartment heats by natural gas. The student cooks a meal using two gas burners that each emit carbon monoxide (CO) at a rate of 100 mg/hr. The outdoor CO concentration can be assumed to be negligible (0 ppm). The initial (time = 0) indoor CO concentration can be assumed to be 0 ppm (except for problem 4). Carbon monoxide can be considered as an inert gas, i.e., it does not stick to or react with any surfaces or other gases in air.
1. Assume that the student cooks for a long enough period of time to achieve a steady-state CO concentration in the apartment. What is that concentration in ppb?
2. Assume that the student cooks for only 45 minutes and turns off both burners at that time. What is the CO concentration in ppb at the end of 45 minutes?
3. Repeat problem 2 for air exchange rates that vary from 0.1 to 1/hr and plot the concentration at 45 minutes (in ppb) versus air exchange rate.
4. Assume that for the conditions of problem 2, the student waits 25 minutes after turning the burners off and then starts cooking again with two burners on. How long will it take to reach a concentration that is 95% of steady-state under this condition?

First, let's determine the total number of fuses in each toolbox:
First Toolbox:
Total fuses = 4 white fuses + 3 black fuses = 7 fuses
Second Toolbox:
Total fuses = 3 white fuses + 5 black fuses = 8 fuses
(a) The probability that the fuse drawn from the second toolbox is black:
The probability of drawing a black fuse from the second toolbox depends on the fuse selected from the first toolbox. There are two scenarios to consider:
Scenario 1: The fuse selected from the first toolbox is black.
In this case, the second toolbox will have 3 black fuses remaining out of the total 7 fuses.
Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)
Probability = 3/7
Scenario 2: The fuse selected from the first toolbox is white.
In this case, the second toolbox will have 5 black fuses out of the total 7 fuses.
Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)
Probability = 5/7
To calculate the overall probability, we need to consider the probability of each scenario and weigh it by the probability of selecting a fuse of that color from the first toolbox. Since the fuse from the first toolbox has an equal chance of being white or black, we need to take an average of the probabilities in both scenarios.
Probability of drawing a black fuse from the second toolbox = (Probability of scenario 1 + Probability of scenario 2)/2
Probability of drawing a black fuse from the second toolbox = (3/7 + 5/7)/2
Probability of drawing a black fuse from the second toolbox = 8/14
Probability of drawing a black fuse from the second toolbox = 4/7
Therefore, the probability of drawing a black fuse from the second toolbox is 4/7.
(b) The probability that the fuse drawn from the second toolbox is white:
Similarly, we can calculate the probability of drawing a white fuse from the second toolbox. It will be the complement of the probability of drawing a black fuse.
Probability of drawing a white fuse from the second toolbox = 1 - Probability of drawing a black fuse from the second toolbox
Probability of drawing a white fuse from the second toolbox = 1 - 4/7
Probability of drawing a white fuse from the second toolbox = 3/7
Therefore, the probability of drawing a white fuse from the second toolbox is 3/7.
(c) The probability that one is white:
To calculate the probability that one fuse is white, we need to consider both scenarios: either the fuse drawn from the first toolbox is white and the fuse drawn from the second toolbox is black, or the fuse drawn from the first toolbox is black and the fuse drawn from the second toolbox is white.
Scenario 1: Fuse drawn from the first toolbox is white, and the second toolbox has a black fuse:
Probability = (Probability of drawing a white fuse from the first toolbox) * (Probability of drawing a black fuse from the second toolbox)
Probability = (3/7) * (5/7)
Scenario 2: Fuse drawn from the first toolbox is black, and the second toolbox has a white fuse:
Probability = (Probability of drawing a black fuse from the first toolbox) * (Probability of drawing a white fuse from the second toolbox)
Probability = (4/7) * (3/7)
To calculate the overall probability, we need to sum up the probabilities of both scenarios:
Probability that one fuse is white = Probability
of scenario 1 + Probability of scenario 2
Probability that one fuse is white = (3/7) * (5/7) + (4/7) * (3/7)
Probability that one fuse is white = 15/49 + 12/49
Probability that one fuse is white = 27/49
Therefore, the probability that one fuse is white is 27/49.

1. A 150 v moving iron voltmeter is intended for 50HZ, has a resistance of 3kQ. Find the series resistance required to extent the range of instrument to 300v. If the 300V instrument is used to measure a d.c. voltage of 200V. Find the voltage across the meter?
Answer:
Voltmeter reactance = 2π × 50 × 0.7 = 220ΩImpedance of voltmeter = 3000 + j220 = 3008Ω When the voltmeter range is doubled its impedance has also to be doubled in order to have the same current for full-scale deflection. If R is the required series resistance then 3000 + R2 + 2202 = 2 × 30082 ∴ R = 3012Ω When used on d.c. supply if the voltmeter reads 200 V the actual applied d.c. voltage would be = 200 × Total A.C. Impedance/total d.c. resistance = 200 × 2 × 3008/3000 + 3012 = 200 × 6016 × 6012 = 200.134V.

if a steam gauge is located 15 ft. above the steam header and if the gauge reads 450 psi, what is the pressure in the steam line?
The pressure in the steam line is 1,44 atm.
Streamlined defined as a graph showing the pressure at which a liquid and its vapor are in equilibrium at any temperature. Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of enhancement in efficiency with enhancement in pressure becomes less as the pressure enhances. The steam work through from the boiler into the steam mains. Firstly, the pipework is cold and heat is transformed into it from the steam. The air surrounding the pipes is also cooler rather than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.
The height of a steam gauge = 15 ft = 4,572 m
the gauge reads 450 psi
1 psi = 14.7 atm
450 psi = 6,615 atm
We can use this formula to calculate the pressure:
P = F/h
Pressure (P) = 6,615 atm : 4,572 m = 1,44 atm
