In a test of hypotheses Ho : µ = 456 versus H1 : µ < 456, the rejection region is the interval (-0, -1.796], the value of the sample mean computed from a sample of size 12 is ī = 453, and the value of the test statistic is t = -2.598. The correct decision and justification are: (a) Do not reject Ho because the sample is small. (b) Do not reject Ho because -2.598 < -1.796. (c) Reject Ho because 453 is less than 456. (d) Reject Ho because -2.598 is negative. (e) Reject Ho because -2.598 lies in the rejection region.
