A data set includes data from student evaluations of courses. The summary statistics are n= 85, x = 3.65, s = 0.59. Use a 0.01 significance level to test the claim that the population of student course evaluations has a mean equal to 3.75. 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.

A data set includes data from student evaluations of courses. The summary statistics are n = 85, x = 3.65, s = 0.59. Use a 0.01 significance level to test the
claim that the population of student course evaluations has a mean equal to 3.75. 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?
Ο Α. Η0: μ= 3.75
H1: µ<3.75
B. H0: μ 3.75
H4:µ> 3.75
C. Ho: H#3.75
H1: H = 3.75
D. H0: μ= 3.75
H1: µ#3.75
Determine the test statistic.
(Round to two decimal places as needed.)
