25. In finding the areas under the normal curve, if we wish to determine the area above A, and A is greater than the mean, we?

A) we find the area below A on the positive Z table and subtract it from .5000.

B) we find the area below A on the positive Z table and subtract it from 1.000.

C) the positive Z table gives us the area above A

D) we find the area below A on the negative Z table

26. In finding the areas under the normal curve, if we wish to determine the area below A, and A is greater than the mean, we ?

A) we find the area below A on the positive Z table and subtract it from .5000.

B) we find the area below A on the positive Z table and subtract it from 1.000.

C) the positive Z table gives us the area belowA

D) we find the area below A on the negative Z table

Solution

25.

A is greater than the mean, hence a positive z score.

Thus, we:

OPTION B: we find the area below A on the positive Z table and subtract it from 1.000. [ANSWER]

26.

The table readily gives left tailed areas. Thus,

OPTION C: The positive Z table gives us the area below A.
