Use the Z table to find the probability associated with each of the following areas under a normal curve:
a. Above a z-score of 1.67
b.Above a z-score of–1.35
Homework Answers
Solution:
a)
Area above a z-score of 1.67
= P(Z > 1.67)
= 1 - P(Z < 1.67)
= 1 - 0.9525
= 0.0475
b)
Area above a z-score of–1.35
= P(Z > -1.35)
= 1 - P(Z < -1.35)
= 1 - 0.0885
= 0.9115

Use a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area
Use a table of cumulative areas under the normal curve to find the z-score that corresponds to the given cumulative area. If the area is not in the table, use the entry closest to the area. If the area is halfway between two entries, use the z-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score.0.049The cumulative area corresponds to the z-score of _______
