A data set includes data from student evaluations of courses. The summary statistics are n = 87, x = 3.34, s 0.67. Use a 0.05 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. There are two requirements that must be checked and met in order to test a claim about a population mean when the population standard deviation is not known using the Student t distribution. The first is that the sample is a simple random sample. For this problem, it is stated to assume that the sample is a simple random sample.
