A data set includes data from student evaluations of courses. The summary statistics are n=95, x= 3.33, s=0.66. Use a 0.10 significance level to test the claim that the population of student course evaluations has a mean equal to 3.50. 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. Hp: H=3.50 H:u<3.50 О в. Но: и3.50 H: u23.50 OC. Ho: Hz3.50 H:p=3.50 OD. Ho: =3.50 H: u>3.50 Determine the test statistic. (Round to two decimal places as needed.) Determine the P-value. (Round three decimal places as needed.) State the final conclusion that addresses the original claim. v Ho. There is v evidence to conclude that the mean of the population of student course evaluations is equal to 3.50 v correct.
