use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5% significant level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal. Test Ho: µ=20 vs Ho: µ ≠ 20 using the sample results 1 = 15.3, s = 7.7, with n = 15. GIVE THE TEST STATISTIC : WITH A CRITICAL VALUE OF 2.145, DETERMINE A CONCLUSION AND INTERPRET.
