Homework Answers
We can increase the rejection region by increasing the level of significance.
For example, in a right tailed test, the area of rejection region at 5% level of significance is less than the area of rejection region at 10% level of significance.
Therefore the given statement is true

1) In hypothesis testing, the region of rejection of the null hypothesis will always be smaller than the region of acceptance of the null hypothesis. True or False? One-sample tests use data drawn from a single sample to test that the sample comes from a specified population. True or False?
