A data set includes data from student evaluations of courses.
A data set includes data from student evaluations of courses. The summary statistics are n = 89, x̅= 3.34, s=0.51. 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?
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.
