Section 2: In Exercises 13-16, use a t-test to test the claim about the population mean u at the given level of significance a using the given sample statistics. For each claim, assume the population is normally distributed. 13. Claim: / = 15; a = 0.01. Sample statistics: x - 13.9, s - 3.23, n = 6 14. Claim: / > 25; a = 0.05. Sample statistics: x - 26.2, s - 2.32, n = 17 15. Claim: / 2 8000; a = 0.01. Sample statistics: x - 7700, s = 450, n - 25 16. Claim: / # 52,200; a = 0.10. Sample statistics: x - 53,220, s - 2700, n = 18
