Question

If Z is a standard normal variable, find the probability
-P(Z > 0.59)
A)0.2190
B)0.2224
C)0.2776
D)0.7224

Quizplus · Accepted Answer

DThe probability that Z is greater than 0.59 is found by subtracting the cumulative probability up to 0.59 from 1. The cumulative probability up to 0.59 (P(Z < 0.59)) is approximately 0.7224, so P(Z > 0.59) = 1 - 0.7224 = 0.2776. Therefore, options C and D are correct, with C giving the correct probability and D providing the cumulative probability used in the calculation.
