Transcribed Image Text:A data set includes data from student evaluations of courses. The summary statistics are n 89, x 3.65, s 0.62. Use a 0.10 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 altemative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.
What are the null and altemative hypotheses?
O A. Ho =3.75
O B. Ho -3.75
H, p+3.75
H, p<3.75
O C. Ho =3.75
H u> 3.75
O D. Ho u3.75
H-3.75
