Question
A data set includes data from student evaluations of courses. The summary statistics are n = 96, x= 3.84, s= 0.69. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. 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? Ο Α. Ηγ: μ = 4.00 Hy:μ > 4.00 O C. Ho: μ#4.00 H₁: =4.00 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. Fail to reject Ho. There is G OB. Ho: μ = 4.00 H₁: μ#4.00 O D. Ho: μ= 4.00 H,:μ < 4.00 ✔ evidence to conclude that the mean of the population of student course evaluations is equal to 4.00 ▼correct.
