# Hypothesis Testing Rejection and P-Values

Consider the hypothesis test given by

H0: u =530

H1: u does not = 530

In a random sample of 85 subjects, the sample mean is found to be 522.3. Also, the population standard deviation is 29.

Determine the p-value for this test. Is there sufficient evidence to justify the rejection of H0 at the "alpha" level of 0.01? Please explain your answer.
