A data set includes data from student evaluations of courses. The summary statistics are n=93, x̅=3.85, 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 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? A. H0: μ≠ 4.00 H1: μ= 4.00 B. H0: μ= 4.00 H1: μ>4.00 C. H0: μ=4.00 H1: μ≠4.00 D. H0: μ=4.00 H1: μ<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. ___ (Redject or Fail to Reject) H0. There is _____ (not sufficent or sufficent) evidence to conclude that the original claim that the mean of the population of student course evaluations is equal to 4.00 _____ (is or is not) correct.

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. H0: μ≠ 4.00 H1: μ= 4.00
B. H0: μ= 4.00 H1: μ>4.00
C. H0: μ=4.00 H1: μ≠4.00
D. H0: μ=4.00 H1: μ<4.00
Determine the test statistic
_____ (Round to two decimal places as needed.)
Determine the P-value.
