Question 5: Please advise.

Consider the hypotheses shown below. Given that x = 115, o = 27, n = 49, a = 0.10, complete parts a through c below. Ho: H = 121 HA: H # 121 . . . a. State the decision rule in terms of the critical value(s) of the test statistic. Reject the null hypothesis if the calculated value of the test statistic, is the critical value(s), . Otherwise, do not reject the null hypothesis. (Round to two decimal places as needed. Use a comma to separate answers as needed.) b. State the calculated value of the test statistic. The test statistic is (Round to two decimal places as needed.) c. State the conclusion. Because the test statistic the null hypothesis and conclude the population mean equal to 121
