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: mu=120 vs mu less than 120 using the sample stat xbar=112.3, s=18.4 and n=100. Whats the p vale?
