You are given H0: μ = 40, H1: μ ≠ 40, if the decision rule is: Reject H0 if t > 1.9925 or t < -1.9925. If the sample mean equals 38.2, the sample standard deviation = 2.7, and n = 75, can you reject the null hypothesis? a. Yes, because the test statistic value does not fall in the rejection region. b. No, because the test statistic value does fall in the rejection region. c. Yes, because the test statistic value does fall in the rejection region. d. No, because the test statistic value does not fall in the rejection region.
