Click here to view page 1 of the table of the critical values of t Click here to view page 2 of the table of the critical values of t. Determine the critical value(s) The critical value(s) is(are) (Round to four decimal places as needed. Use a comma to separate answers as needed.) Determine the test statistic, teTAT- tSTAT =O (Round to four decimal places as needed.) State your statistical decision. Choose the correct answer below. O A. The test rejects the null hypothesis. The data does not provide sufficient evidence O B. The test does not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u= 50. O C. The test rejects the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50. O D. The test does not reject the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u= 50. conclude that the mean differs from u = 50.
