Hypotheses and summary sample statistics are given for a test for a mean. Assume that the conditions are met and the underlying distribution is approximately normal. Test Ho: = 80 vs Ha: 80 when the sample has X = 85 with 5 = 24.3 and n = 12. Find the value of the t-test statistic and then use the t -distribution to find the P-value.. Round your answers to three decimal places. test statistic = P-value = What is the conclusion using a 5% significance level? Reject Ho. Do not reject Ho.
