H0: X̄ ≤ 30 versus H1: X̄ > 30
True or False: Suppose, in testing a hypothesis about a proportion, the p-value is computed to be 0.034. The null hypothesis should be garbage if the liked level of significance is 0.01.TrueFalse
True or False: The smaller sized is the p-value, the more powerful is the evidence versus the null hypothesis.TrueFalse
