A data set includes data from student evaluations of courses. The summary statistics are n = 92, x = 4.16, s = 0.57. Use a 0.10 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: =4.25 H: u<4.25 O B. Ho: =4.25 H: u>4.25 D. Ho:=4.25 OC. Ho: H#4.25 H:u=4.25 H1: u#4.25 Determine the test statistic. O (Round to two decimal places as needed.)
