a. Determine the critical value(s). The critical value(s) is(are) (Round to three decimal places as needed. Use a comma to separate answers as needed.) Determine the test statistic, t-. (Round to two decimal places as needed.) What conclusion should be drawn? Choose the correct answer below. O A. Do not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u= 50. O B. Do not reject the null hypothesis. The data do not provide sufficient evidence to conclude that the mean differs from u= 50. OC. Reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from p= 50. O D. Reject the null hypothesis. The data do not provide sufficient evidence to conclude that the mean differs from p= 50. b. Use technology to determine the p-value for this test. What is the p-value? p-value = (Round to three decimal places as needed.)
