Solutions

Expert Solution

The area that lies below the Z score of a standard normal curve is the probability of the score that has the corresponding Z score.

This area can be calculated using the excel formula for normal distribution which takes the Z score as a parameter.

a) At Z = 0.53, the excel formula used is =NORM.S.DIST(0.53, TRUE), thus the probability score is computed as:

Probability = 0.7019

b) At Z = 0.0.24, the excel formula used is =NORM.S.DIST(0.24, TRUE), thus the probability score is computed as:

Probability = 0.5948

c) At Z = 1.08, the excel formula used is =NORM.S.DIST(1.08, TRUE), thus the probability score is computed as:

Probability = 0.8599

d) At Z = -1.39, the excel formula used is =NORM.S.DIST(-1.39, TRUE), thus the probability score is computed as:

Probability = 0.0823

The probabilities can also be calculated using the Z score table that is;
