If, in a sample of n = 30 selected from a normal population, X = 53 and S = 12, what is your statistical decision if the level of significance, a, is 0.10, the null hypothesis, Ho, is u = 50, and the alternative hypothesis, H,, is u # 50?

(Round to four decimal places as needed. Use a comma to separate answers as needed.) Determine the test statistic, tSTAT. STAT = (Round to four decimal places as needed.) State your statistical decision. Choose the correct answer below. O A. The test does not reject the null hypothesis. The data does not provide sufficient evidence to conclude that the mean differs from u = 50. O B. The test rejects 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 does not provide sufficient evidence to conclude that the mean differs from u = 50. O D. The test does not reject the null hypothesis. The data provide sufficient evidence to conclude that the mean differs from u = 50
