Question

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 $H_0 : mu = 4$ vs $H_a : mu eq 4$ using the sample results $ar{x} = 4.8, s = 2.3$, with $n = 15$. (a) Give the test statistic and the p-value. Round your answer for the test statistic to two decimal places and your answer for the p-value to three decimal places. test statistic = p-value = (b) What is the conclusion? Reject $H_0$. Do not reject $H_0$.
