Question

Use a table of cumuliative areas under the normal curve to find the z-score that corresponds to the given cumulative area. If closest to the area. If the area is halfway between two entries, use the z-score haMway between the corresponding 2-scores, r z-score to the given cumulative area. If the area is not in the table, use the entry between the corresponding z-scores. If convenient, use technology to find the 0.053 The cumulative area corresponds to the z-score of (Round to three decimal places as needed.)

Explanation / Answer

Using the excel function NORM.S.INV(probability)

setting the probability = 0.053

The excel function gives us NORM.S.INV(0.053) = -1.616

So, the required value of z score corresponding to the cumulative area is -1.616 (rounded to 3 decimals)
