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.
