P.S. I couldn't show my work bc i cant take a picture of it.
Answer:
Part 1 and 2:
A. Forearm (in) Foot (in)
Sarah 10 9
Sam 11. 10
Emma 8 7
Mom 10 9
Dad 11 10
B. M=9-7 over 8-10 the answer is 2 over 2.
C. For every forearm the foot is one inch smaller.
Part 3:
A. 0.860(17)+3.302
B. Y=17.922. They are slightly different. Keren’s has a greater rate. I think the values are different because they have different origins.
C. Yes, because it is an important part for rate of change. Yes it is a function because there can’t be any exponents greater than 1, and its not a straight line if you plug it in.
Step-by-step explanation:
This is just an example dont you the names
C is the value of x to find it u use the equation 3x=338 and solve

Check Explanation
Step-by-step explanation:
A) The null hypothesis would be that the proportion of newly hired candidates that are not white is not significantly different from the proportion of the applicants that are not white & there is no significant evidence that the company's hiring practices are discriminatory.
Mathematically,
H₀: μ₀ = 0.53
And the alternative hypothesis would be that there is a significant difference between the proportion of newly hired candidates that are not white is not significantly different from the proportion of the applicants that are not white. More specifically, that the proportion of newly hired candidates that are not white is significantly less than the proportion of applicants that are not white & there is significant evidence that the company's hiring practices are indeed discriminatory.
Mathematically,
Hₐ: μ₀ < 0.53
B) The two errors that can come up in this hypothesis testing include -
Type I error: We reject the null hypothesis because we obtain that the proportion of newly hired candidates that are not white is significantly less than the proportion of applicants that are not white and conclude that there is indeed significant evidence that the company's hiring practices are discriminatory when in reality, there is no significant difference and hence, no discrimination.
Type II error: We accept the null hypothesis (fail to reject the null hypothesis) because we obtained that there is no significant difference between the proportion of newly hired candidates that are not white & th proportion of applicants that are not white and conclude that there is no discrimination in the company's hiring practices when in reality, there is significant difference in the stated proportions above and significant evidence that there is indeed significant evidence that the company's hiring practices are discriminatory.
C) The power of the test increases as the significance level reduces. This is because t-statistic increases as significance level reduces.
D) The standard error of the mean used in computing the t-score is given as
σₓ = (σ/√n)
It is evident that as the value of n increases, the standard error reduces and this widens the effect of the test, hence, the power of the test increases.

Answer:
Mean = £1.8 million
Step-by-step explanation:
The MEAN is the sum of all the numbers divided by the number of numbers.
- <u>There are 5 numbers in total</u>
- <u>The sum is
million</u>
Hence the mean is
million
