So, the pairs of numbers that would represent the simple main effect of therapy (factor a) at the group setting (b2) in this example would be a1b2 (cognitive-behavioral therapy at the group setting) and a2b2 (relaxation therapy at the group setting).

In a 2x2 factorial design, there are two independent variables, each with two levels. This means that there are a total of four treatment conditions in the experiment. The simple main effect of one of the independent variables (in this case, factor a) at a specific level of the other independent variable (in this case, b2) refers to the effect of that independent variable on the dependent variable when the other independent variable is held constant at a specific level.

To understand this concept more clearly, let's consider an example. Suppose that in your experiment, factor a is the type of therapy (cognitive-behavioral therapy vs. relaxation therapy) and factor b is the type of treatment setting (individual vs. group). In this case, the simple main effect of therapy (factor a) at the group setting (b2) would refer to the effect of therapy on the dependent variable when the treatment setting is held constant at the group level.

The simple main effect of therapy (factor a) at the group setting (b2) would be calculated by comparing the mean response for the cognitive-behavioral therapy condition (a1b2) to the mean response for the relaxation therapy condition (a2b2). This would allow you to determine whether there is a significant difference in the mean response between the two therapy conditions when the treatment setting is held constant at the group level.

So, to answer your question, the pairs of numbers that would represent the simple main effect of therapy (factor a) at the group setting (b2) in this example would be a1b2 (cognitive-behavioral therapy at the group setting) and a2b2 (relaxation therapy at the group setting).

Answer:

P ∝ d

P ∝ 1/t

Using this information, we can establish a formula:

P = Kd/t  , where K is some constant

We need to determine that constant using the initial conditions.

d = 2100 ft

t = 70 s

P = 180 KW

K = Pt/d

K = [(180 kW)(70s)] / 2100 ft

K = 6 kW s / ft

We can now find the distance of the car when P = 204 kW and t = 90s

P = Kd/t

d = Pt/K

d = [(204 kW)(90 s)] / (6 kWs /ft)

d = 3060 ft

The total perimeter of the given composite figure is; 74.55 meters

The perimeter of the given figure can be calculated by dividing the figure into two parts : One is semi-circle and second is rectangle.

To find Perimeter of rectangle :

Length of the rectangle = 18 m

Width of the rectangle = 15 m

Perimeter = (2 × Length) + Width

Perimeter = (2 × 18) + 15

Perimeter = 36 + 15

Perimeter = 51 meters

To find perimeter of semi-circle :

Radius of semi-circle = 15/2 = 7.5 m

Perimeter of semi-circle = π × radius

Perimeter = 3.14 × 7.5

Perimeter = 23.55 meter

Based on the given information, the second brand, Cola, is the more affordable option in terms of cost per milliliter compared to Co Fizz.

To determine which brand of cola is more expensive, we need to compare the cost per unit volume for each brand.

For the first brand, Co Fizz, a pack contains 4 bottles, and each bottle has a volume of 500 ml. The cost of the pack is $2.50. Therefore, the total volume in a pack is 4 * 500 ml = 2000 ml. To find the cost per milliliter (ml), we divide the total cost by the total volume: $2.50 / 2000 ml = $0.00125 per ml.

For the second brand, Cola, a pack contains 10 bottles, and each bottle has a volume of 330 ml. The cost of the pack is $2. Therefore, the total volume in a pack is 10 * 330 ml = 3300 ml. To find the cost per milliliter (ml), we divide the total cost by the total volume: $2 / 3300 ml ≈ $0.000606 per ml.

Comparing the two brands, we can see that the cost per milliliter for Co Fizz is $0.00125, while the cost per milliliter for Cola is approximately $0.000606.

Since the cost per milliliter for Co Fizz is higher than the cost per milliliter for Cola, it can be concluded that Co Fizz is more expensive in terms of price per unit volume.

Answer:

a) 20.44% probability that none of the selected adults say that they were too young to get tattoos.

b) 35.90% probability that exactly one of the selected adults says that he or she was too young to get tattoos.

c) 56.34% probability that the number of selected adults saying they were too young is 0 or 1.

d) No

Step-by-step explanation:

For each adult, there are only two possible outcomes. Either they say they were too young when they got their tattoos, or they don't say that. Each adult is independent of each other. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

18% say that they were too young when they got their tattoos.

This means that \(p = 0.18\)

Eight adults who regret getting tattoos are randomly selected

This means that \(n = 8\)

a. Find the probability that none of the selected adults say that they were too young to get tattoos.

This is P(X = 0).

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{8,0}.(0.18)^{0}.(0.82)^{8} = 0.2044\)

20.44% probability that none of the selected adults say that they were too young to get tattoos.

b. Find the probability that exactly one of the selected adults says that he or she was too young to get tattoos.

This is P(X = 1).

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 1) = C_{8,1}.(0.18)^{1}.(0.82)^{7} = 0.3590\)

35.90% probability that exactly one of the selected adults says that he or she was too young to get tattoos.

c. Find the probability that the number of selected adults saying they were too young is 0 or 1.

Either a. or b.

20.44 + 35.90 = 56.34

56.34% probability that the number of selected adults saying they were too young is 0 or 1.

d. It we randomly select 9 adults. Is 1 a significantly low number who day that they were too young to get tattoos?

Now \(n = 9\)

It is significantly low if it is more than 2.5 standard deviations below the mean.

The mean is \(E(X) = np = 9*0.18 = 1.62\)

The standard deviation is \(\sqrt{V(X)} = \sqrt{n*p*(1-p)} = \sqrt{9*0.18*0.82} = 1.15\)

1 > (1.62 - 2.5*1.15)

So the answer is no.

Answer:

Step-by-step explanation:

Given that:

The numbers of the possible public swimming pools are 5

From past results, we have 0.007 probability of finding bacteria in a public swimming area.

In the public swimming pool, the probability of not finding bacteria = 1 - 0.007

= 0.993

Thus;

Probability of combined   =  Probability that at least one public

sample with bacteria           swimming area have bacteria

Probability of combined sample with bacteria  = 1 - P(none out of 5 has          

                                                                                bacteria)

Probability of combined sample with bacteria = 1 - (0.993)⁵        

= 1 - 0.9655

= 0.0345

Thus, the probability that the combined sample from five public swimming areas will show the presence of bacteria is 0.0345

From above, the probability that the combined sample shows the presence of bacteria is 0.0345 which is lesser than 0.05.

Thus, we can conclude that;  Yes, the probability is low enough that there is a need for further testing.

The problem lies in that \(a=b\).

Looking at your fourth line of work, \((a+b)(a-b)=b(a-b)\)

You divided by \((a-b)\).

And because \(a=b\), \(a-b=0\)

P=160-70*cos(2π*(1/12)*t)

• Pressure in mathematics or physics is defined as force per unit area. The pressure exerted by a solid object which is resting on top of a solid surface is the weight divided by the area of the object . SI unit of force is Newton (N).

First, we find the amplitude by taking the difference between the peak values and dividing by two:

Amplitude=(230+90)/2=70

We can find the center value by either adding 70 to the minimum or subtracting 70 from the maximum:

90+70=160

230-70=160

This tells us that the Center Value=160

The frequency that we are operating at is given as:

f = 5/hour

so in minutes

f=5*(1/60)/minute=5/60=1/12 per minute

Answer:

Mean = 59.1, Median = 61

(there might have been a mistake in calculation (a lot of numbers!))

Step-by-step explanation:

The sample size is 40,

Now, the formula for the mean is,

Mean = (sum of the sample values)/(sample size)

so we get,

\(Mean = (49+63+78+22+41+39+75+61+63+65+58+37+45+52+81+75+78+72+68+59+72+85+63+61+75+39+41+48+59+55+61+25+61+52+58+71+75+82+49+51)/40\\Mean = 2364/40\\Mean = 59.1\)

To find the median, we have to sort the list in ascending (or descending)order,

we get the list,

22,25,37,39,39,41,41,45,48,49,

49,51,52, 52,55,58, 58, 59, 59, 61,

61, 61, 61, 63, 63, 63, 65, 68, 71, 72,

72, 75, 75, 75, 75, 78, 78, 81, 82, 85

Now, we have to find the median,

since there are 40 values, we divide by 2 to get, 40/2 = 20

now, to find the median, we takethe average of the values above and below this value,

\(Median = ((n/2+1)th \ value + (n/2)th \ value )/2\\where, \ the\ (n/2)th \ value \ is,\\n/2 = (total \ number \ of \ samples) /2\\n/2=40/2\\(n/2)th = 20\\Hence\ the (n/2)th \ value \ is \ the \ 20th \ value\)

And the (n+1)th value is the 21st value

Now,

The ((n/2)+1)th value is 61 and the nth value is 61, so the median is,

Median = (61+61)/2

Median = 61

Answer:

0.159

Step-by-step explanation:

Given that:

Sample size (n) = 100

Population mean(pm) = 50

Standard deviation (s) = 8

Probability that Sample mean (m) will be greater Than 50.8

Using the relation :

(sample mean - population mean) / (standard deviation /sqrt(n))

P(m > 50.8)

Z = (50.8 - 50) / (8/ sqrt(100))

Z = 0.8 / (8/ 10)

Z = 0.8 / 0.8

Z = 1

P(Z > 1) = 0.15866 ( Z probability calculator)

Hence,

P(Z > 1) = 0.159 ( 3 decimal places)

The probability that a sample mean will be greater than 50.8 is P(Z > 1) = 0.159.

Given that,

Suppose that a random sample of size 100 is to be selected from a population with a mean of 50 and a standard deviation of 8.

We have to determine,

What is the probability that a sample mean will be greater than 50.8?

According to the question,

Sample size (n) = 100

Population mean(pm) = 50

Standard deviation (s) = 8

The probability that Sample mean (m) will be greater than 50.8.

Therefore,

\(\dfrac{(sample \ mean - population \ mean) \times \sqrt{n}}{standard \ deviation}\)

Where P(m > 50.8)

\(Z = \dfrac{50.8 - 50 \times \sqrt{100}}{8}\\\\Z =\dfrac{ 0.8 \times 10 }{8}\\\\Z = \dfrac{0.8 }{0.8}\\\\Z = 1\)

P(Z > 1) = 0.15866 ( Z probability calculator)
