In a test of hypotheses Ho: M = 456 versus H1:4< 456, the rejection region is the interval (-00, -1.796], the value of the sample mean computed from a sample of size 12 is x = 453, and the value of the test statistic is t = -2.598. The correct decision and justification are: O Reject Ho because 453 is less than 456 O Reject Ho because -2.598 lies in the rejection region O Do not reject Ho because -2.598...
