Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5% significance level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal. test h0 : μ=100 vs ha : μ < 100
X bar is 91. 7, s= 12.5 and n= 30
Give the test statistic and the p-value
