A data set includes data from student evaluations of courses. The summary statistics are n = 84, x = 4.08, s = 0.52. 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? A. Ho =4.25 H: >4.25 C. Ho: 4.25 H: =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 B. Ho: =4.25 : < 4.25 D. Ho: = 4.25 H: 4.25 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.
