A data set includes data from student evaluations of courses. The summary statistics are n= 88, x= 4.09, s = 0.66. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative hypotheses? O A. Ho: u= 4.25 O B. Ho: u=4.25 H: u<4.25 H;: u#4.25 OC. Ho: u#4.25 H: u= 4.25 O D. Ho: u= 4.25 H: u>4.25 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. V Ho. There is evidence to conclude that the mean of the population of student course evaluations is equal to 4.25 correct.

A data set includes data from student evaluations of courses. The summary statistics are n= 88, x=4.09, s 0.66. Use a 0.05 significance level to test the claim that the population of student
course evaluations has a mean equal to 4.25. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final
conclusion that addresses the original claim.
What are the null and alternative hypotheses?
O A. Ho: H=4.25
H, p<4.25
O B. Ho: p=4.25
H4: µ+4.25
O C. Ho- p 4.25
H,p=4.25
O D. Ho p= 4.25
H p>4.25
Determine the test statistic.
(Round to two decimal places as needed.)
Determine the P-value.
Round to three decimal places as needed.)
State the final conclusion that addresses the original claim.
Ho- There is
evidence to conclude that the mean of the population of student course evaluations is equal to 4.25
correct.
