Question

Given that Z is a standard normal random variable, P(Z > 1.75) is:

a) 0.94
b) 0.52
c) 0.04
d) 0.02
e) None of the above.

Answer 1

The probability P(Z > 1.75) is approximately 0.0409.

Step-by-step explanation:

To find the probability P(Z > 1.75) where Z is a standard normal random variable, we can subtract the area to the left of 1.75 from 1. Using the z-table, we find that the area to the left of 1.75 is 0.9591. Subtracting this from 1, we get 0.0409. Therefore, P(Z > 1.75) is approximately 0.0409.
