Question

With alpha = 0.05, how are the boundaries for the critical region determined?

SELECT THE CORRECT ANSWER
Boundaries are drawn so each distribution tail has 10% (.10).

Boundaries are drawn, so there is 5% (.05) in the centre of the distribution.

Boundaries are drawn so each distribution tail has 5% (.05).

Boundaries are drawn, so 2.5% (.025) is in each distribution tail.

Answer 1

In hypothesis testing, when you have a significance level (alpha) of 0.05 for a two-tailed test, the boundaries for the critical region are determined such that there is 2.5% in each tail of the distribution.

Therefore, the correct answer is:

**Boundaries are drawn, so 2.5% (.025) is in each distribution tail.**
