Use the t-distribution and the sample results to complete the test of the hypotheses. Use a 5 % significance level. Assume the resultscome from a random sample, and if the sample size is small, assume the underlying distribution is relatively normal.Test Ho μ = 4vs Hau 4 using the sample results=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 thtest statistic =p-value = 1value to three decimal places.
