Let A and B be constants such that A < B. Let z be a standard normal

random variable. For what values of A does P(A<z<B)approximately

equal P(z<B)?

Pick ALL that apply.

a. A = -9

b. A = -26

c. A = 0

d. A = 9

e. None of these are correct.

This is how I'm reasoning this question:

B is not specified, but B > A.

a) A=-9, let B=-8.9

So, that's why I think the answer would be A and B. But I have a feeling I

am wrong.
