Question

(1) Inference from a two-sided hypothesis test may be different that inference from a one-sided hypothesis test (at the same significance level).

a. TRUE
b. FALSE
  
(2) The critical region for a two-sided hypothesis test is twice as large as the critical region for a one-sided hypothesis test.

a. TRUE
b. FALSE
  
(3) If we reject a claim for a two-sided hypothesis test, then we reject the same claim for a one-sided hypothesis test (at the same significance level).

a. TRUE
b. FALSE

Answer 1

Solution:-

(1) Inference from a two-sided hypothesis test may be different that inference from a one-sided hypothesis test. (a) TRUE

It might happens we are rejecting a claim for two-sided hypothesis test, but we failed to reject the same claim a one-sided hypothesis test.
(2) The critical region for a two-sided hypothesis test is twice as large as the critical region for a one-sided hypothesis test. (a) TRUE
(3) If we reject a claim for a two-sided hypothesis test, then we reject the same claim for a one-sided hypothesis test (at the same significance level). (b) FALSE

It might happens we are rejecting a claim for two-sided hypothesis test, but we failed to reject the same claim a one-sided hypothesis test.
