A data set includes data from student evaluations of courses. The summary statistics are n=89, x=3.58, s=0.59. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 3.75. 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: μ = 3.75 H₁:μ>3.75 O C. Ho: H=3.75 H₁: μ<3.75 Determine the test statistic. (Round to two decimal places as needed.) O B. Ho: μ#3.75 H₁: p=3.75 D. H₂:μ=3.75 H₁: μ#3.75

A data set includes data from student evaluations of courses. The summary statistics are n= 95, x over bar = 3.44, s= 0.64. 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 is the hypothesis? What is the test statistic? What is the p-value? What is the final conclusion that addresses the original claim? Is there suficient evidence to conclude that the original claim that the mean of the population of student course evaluations is equal to 3.50 is or is not correct?
