Answer:

Step-by-step explanation:

The conditions for conducting one-sample t-procedures are as follows:

1. Random Sample: The data should be obtained from a random sample or a randomized experiment to ensure that it is representative of the population of interest. This condition helps to minimize bias and ensure the validity of statistical inference.

2. Independence: The observations within the sample should be independent of each other. In other words, the values should not be influenced by each other and should be selected or measured independently. Violation of independence can lead to inaccurate results.

3. Normality or Large Sample Size (Central Limit Theorem): The population from which the sample is drawn should follow a normal distribution, or the sample size should be sufficiently large. If the population is known to be normally distributed, there are no specific requirements on the sample size. However, if the population distribution is unknown, the sample size should generally be at least 30 to apply the Central Limit Theorem, which states that the sample mean tends to follow a normal distribution, regardless of the population distribution shape.

4. Outliers: The presence of outliers can have a significant impact on the results of t-procedures. It is important to check for and address any outliers in the data. Outliers can distort the distribution and violate the assumptions of the t-test.

5. Equal Variances (for two-sample t-test): In the case of a two-sample t-test, if comparing two groups, the variances of the two populations should be equal. This assumption is necessary for calculating the correct degrees of freedom and obtaining accurate results. If the variances are not equal, a modified version of the t-test, called the Welch's t-test, can be used instead.

It is important to carefully assess these conditions before conducting one-sample t-procedures to ensure that the results are valid and reliable. Violations of these conditions may require alternative statistical tests or adjustments to the analysis.

Answer:

\(\sqrt{53\\}\)

Step-by-step explanation:

Use the distance equation (\(\sqrt{(x_{2} - x_{1})^2 + (y_{2} - y_{1})^2} = D\)and plug in the values for the distance D

√((-5-2)^2 + (-4 - (-2))^2) = √53

Answer: A function that increases by a factor of 10 over every unit interval in x and starts at f(0)=1 could be represented by the function rule f(x) = 10^x.

This function starts at f(0) = 10^0 = 1 and for every increase of 1 in the input x, the output f(x) increases by a factor of 10. For example:

f(1) = 10^1 = 10

f(2) = 10^2 = 100

f(3) = 10^3 = 1000

and so on.

Another possible function rule could be f(x) = 10x +1 it starts at f(0) = 1 and for every increase of 1 in the input x, the output f(x) increases by a factor of 10. for example:

f(1) = 101 +1 = 11

f(2) = 102 +1 = 21

f(3) = 103 +1 = 31

and so on.

Both functions have similar behavior and answer the given conditions.

Answer:

y = 2x - 5

Step-by-step explanation:

The slope intercept form is : y = mx + b

M = the slope

We need to find two points on this line

Points (3,1) and (4,3) can work

Slope = y2-y1/x2-x1

3-1/4-3 = m = 2

y = 2x + b

Plug in the numbers

1 = 2*3 + b

1 = 6 + b

b = -5

CHECK

3 = 2*4 - 5

3 = 8 - 5

The answer is y = 2x - 5

Answer:

I got for the retail price $367. 50 and for the retail plus tax I got $396.90.

Step-by-step explanation:

To find the retail you have to figure out what 210% of 175 is. To do this you divide 175 by 100. after yiu get that number you multiply it by 210. after you multiply it you should get 367.50 . then to find the retail value plus tax you divide 367.50 by 100 and get 3.675. multiply 3.675 by 8 and then you get 29.40 . add 367.50 and 29.40 and you get $396.90

i. weekly receipts at a clothing boutique

ii. monthly demand for an automotive part

Time series data refers to information collected and recorded at regular intervals over a specific period. In the case of i. weekly receipts at a clothing boutique and ii. monthly demand for an automotive part, both data sets are examples of time series data.

Time series data consists of observations recorded over regular intervals, allowing for the analysis of patterns and trends over time. In i. weekly receipts at a clothing boutique, the data is collected on a weekly basis, providing insights into the boutique's revenue fluctuations over different weeks. Similarly, ii. monthly demand for an automotive part captures the demand for the part on a monthly basis, enabling analysis of monthly variations and seasonal patterns.

On the other hand, iii. quarterly sales of automobiles do not fall under time series data. While it represents sales data, the intervals between measurements are not consistent enough to qualify as time series. Quarterly intervals are less frequent and may not capture shorter-term trends or variations as effectively as weekly or monthly intervals.

The time taken for the ball to fall a distance of 10feet is 1.25secs

Given the function modeled by the height expressed as:

f(t) =-16t² + 35

In order to determine the time taken by the all to fall a distance of 10 feet, hence;

f(t) = 10

10 = -16t² + 35

-16t² = 10 - 35

-16t² = -25

-t² = -25/16

t² = 25/16

t = √25/16

t = 5/4

t = 1.25secs

Hence the time taken for the ball to fall a distance of 10feet is 1.25secs

What in mathematics is a linear equation?

An algebraic equation B. y=mx+b (where m is the slope and b is the y-intercept) containing simple constants and first-order (linear) components, such as the following, is called a linear equation. The above is sometimes called a "linear equation in two variables" where x and y are variables.

                                       An equation with only one variable is called a univariate linear equation. It contains the expression Ax + B = 0. where A and B are any two real numbers and x is an ambiguous variable with only one possible value.

Answer:

x = 2, y = -3

Explanation:

Given the simultaneous equation

7x+4y=2

9x-4y=30​

Add both equations

7x + 9x = 2 + 30

16x = 32

x = 32/16

x = 2

Substitute x = 2 into equation 1

From 1;

7x + 4y = 2

7(2) + 4y = 2

14 + 4y = 2

4y = 2-14

4y = -12

y = -12/4

y = -3

Hence the solution to the equation is (2, -3)

Step-by-step explanation:

The estimated percentage of states with an average per capita income greater than 32.5 k  is:we need to use the ogive (cumulative frequency curve) to determine the percentage of states with an average per capita income greater than 32.5k.

Assuming that the ogive is a continuous curve, we can estimate the percentage by finding the value on the horizontal axis corresponding to the 50% mark on the vertical axis, and then subtracting it from 100%. From the graph, we can see that the 50% mark corresponds to a value of around 30 k, which is between the values for Oklahoma and Pennsylvania. To get a more accurate estimate, we can use linear interpolation between these two data points.

Let's assume that the values for Oklahoma and Pennsylvania are

(x₁,y₁) = (25k,40%) and (x₂,y₂) = (35k,60%)

respectively. Then the equation of the straight line connecting these two points is:

(y-y₁) =(y₂-y₁) / (x₂-x₁) * (x-x₁)

Substituting in the values gives:

y - 40 = (0.6 - 0.4)/(35 - 25) * (x - 25)

y - 40 = 0.02(x - 25)

y = 0.02x - 0.5

To find the value of x that corresponds to the 50% mark, we can set y = 50% and solve for x:

50 = 0.02x - 0.5

0.02x = 50.5

x = 2525

So the estimated value for x is 25.25k. Therefore, the estimated percentage of states with an average per capita income greater than 32.5k is:

scss

Copy code

100% - 40% - (10% * (32.5 - 25.25)/(30 - 25))

= 50.5%

Therefore, we estimate that about 50.5% of the states have an average per capita income greater than 32.5k.
