A data set includes data from student evaluations of courses. The summary statistics are nequals=8484, x overbarxequals=3.693.69, sequals=0.660.66. Use a 0.100.10 significance level to test the claim that the population of student course evaluations has a mean equal to 3.753.75. 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.
b) Determine the test statistic.
c)Determine the P-value.
d) State the final conclusion that addresses the original claim.
reject/fail to reject? Ho. There is sufficient evidence to conclude that the original claim that the mean of the population of student course evaluations is equal to 4.25 is not correct.
