SOLUTION: In a test of hypotheses H0: µ = 342 versus H1: µ > 342, the rejection region is the interval [2.821, ∞), the value of the sample mean computed from a sample of size 10 is 365

Question 929462: In a test of hypotheses H0: µ = 342 versus H1: µ > 342, the rejection region is the interval [2.821, ∞), the value of the sample mean computed from a sample of size 10 is 365, and the value of the test statistic is t = 2.738. The correct decision and justification are:
A Do not reject H0 because the sample size is too small
B Do not reject H0 because 2.738 < 2.821
C Reject H0 because the test statistic falls in the rejection interval
D Reject H0 anytime the sample mean is larger than 342
