In finding the areas under the normal curve, if we wish to determine the area between A and B, and both A and B are greater than the mean (with A further away from the mean than B)

a) We find the area between the mean and A and subtract the area between the mean and B

b) We find the area between the mean and A and add the area between the mean and B

c) We find the area between the mean and A and subtract it from. 50

d) We find the area between the mean and A and add it to. 50

a.

Step-by-step explanation:

A and B both are greater than mean and so A and B lies on the right side of mean. Further it is stated that A is more away from the mean than B. It means that A is greater than B. So, in order to find the area between A and B we have to subtract the area of mean to B from area of mean to A. It can be explain in the notations as

P (B
P (B
Hence, we find the area from mean to A and subtract the area from mean to B.
