alternative, non-directional, alternative, directional

In two-tailed test, the two _________ regions lie at ______ end tails of the normal curve; each part will be half of the ________ value. If alpha = 0.05, the area in each end tail is alpha=0.025. In one-tailed test, the rejection region lies ________ at the left or right end tail of the normal curve.

rejection, both, alpha, either

A one-tailed test shows that the _____ hypothesis be ________ when test value is in critical region on _____ side of the mean.

null, rejected, one

________________ is a type of statistical inference, which examines the claim about a population based on the information obtained in the random sample.
