QUESTION 97

What is the appropriate hypothesis test when you have statements such as "greater than," "exceeds," and "less than"?

		A two-sided test is appropriate since the direction of the difference does not matter.
		A one-sided test is appropriate since the direction of the difference does matter.
		A one-sided test is appropriate because the rejection region is distributed in both "tails".
		A two-sided test is appropriate since because the rejection region is distributed in one "tail".

QUESTION 100

We only need to use the Normal Distribution for statistics tests of our data since most variables follow this distribution in nature.

		True
		False.
