a. 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. 0.046. The cumulative area corresponds to the z-score of

b. Use the Standard Normal Table or technology to find the z-score that corresponds to the following cumulative area. 0.966. The cumulative area corresponds to the z-score of

Use the standard normal table to find the z-score that corresponds to the given percentile. 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. P18. The z-score that corresponds to P18 is
