Do critical regions get larger when a values get smaller?
Solution
critical regions get smaller as values get smaller
let\'s use a two tailed test:
=.10, so rejection region {z : |z| > z(.05) = 1.645}. the rejection region is all z scores less than -
1.645 and all z scores greater than 1.645
=.05, so rejection region {z : |z| > z(.025) = 1.96}. the rejection region is all z scores less than -
1.96 and all z scores greater than 1.96
as you decrease , it becomes harder and harder to disprove the null hypothesis.
