Question

Given that Z is a standard normal random variable, which of the following is the value for P(Z > -1.58)?
A) -0.4429
B) 0.0571
C) 0.5571
D) 0.9429

Quizplus · Accepted Answer

The area to the right of -1.58 on a standard normal distribution table is 0.9429. Since we want P(Z > -1.58) (the probability that Z is greater than -1.58), we take the complement of this area to get 1 - 0.9429 = 0.0571, which is the probability that Z is greater than -1.58. Therefore, the answer is D.
