The hypothesis test that has two rejection regions is called _____________ Group of answer choices

alternative hypothesis test

directional test

non-directional test

one-sided test

null hypothesis test.

In a hypothesis test, the Type I error rate is set to = 0.10.

When the null hypothesis is false, what is the probability of making a Type I error? Put your answer in percentage. If your answer is 12.34% then put 12.34 in the blank.

Consider the hypothesis test LaTeX: H_0: \mu \leq 20H 0 : 20 vs LaTeX: H_1: \mu > 20H 1 : > 20. Suppose the critical z-score is 1.65, and the observed z-score is 1.8. Then there is ________ evidence _________ the claim that the population mean is _______ 20.
