Question

"Given that z is a standard normal random variable, what is the

value of z if the area to the left of z is 0.9582? Select one:
a. -1.73
b. 1.73
c. 0.73
d. -0.73"

Answer 1

The value of z is approximately 1.73.

Step-by-step explanation:

To find the value of z, we need to use the Z-table. The Z-table shows the area to the left of a z-score. In this case, the area to the left of z is given as 0.9582. To locate this area in the Z-table, we look for the closest value that is less than 0.9582. This value corresponds to a z-score of approximately 1.73.
