Question
In a test of hypotheses Ho: H = 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:
O Do not reject HO because the sample size is too small
O Do not reject HO because 2.738 < 2.821
O Reject HO because the test statistic falls in the rejection interval
O Reject HO anytime the sample mean is larger than 342
Reject HO because 365 > 2.821
