Question

When conducting a hypothesis test (or test of significance), select all the true statement.
- assume the alternative hypothesis is true.
- significance level is selected before collecting data.
- None of these
(can be more than one answer)
Select the correct answer for the blank of each of the following statements.

(i) A smaller significance level makes it (choose one: more difficult, easier) to reject the null hypothesis.

(ii) The p-value of a two-tail (or two-side) test is (choose one: twice(double), half of, same as) the p-value of a one-tail (or one-side) test if everything else stays the same.

(iii) It is (choose one: possible, impossible) to make both type I error and type II error in one hypothesis test at the same time.

(iv) Statistical significance (choose one: implies, does not imply) practical significance.
