A data set includes data from student evaluations of courses. The summary statistics are n= 84, x= 4.11, s= 0.56. 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: u#425 H, p=4.25 O B. Ho: u= 4.25 H,: p#4.25 O D. H, u=4.25 OC. Ho u=4.25 H,: u>4.25 H, u<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. V Hg. There is V evidence to conclude that the mean of the population of student course evaluations is equal to 4.25 V correct.
