Use a significance level of α = 0.05 to test the claim that µ ≠ 64.8. The sample data consist of 12 scores for which  = 59.8 and s = 8.7.
Assume that the sample is randomly selected from a population with a normal distribution. Test the given claim by using the traditional method of testing hypotheses, then re-test using the P-value method.
