Question

16. 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 thez-score halfway between the corresponding z-scores. If convenient, use technology to find the z-score.

0.049

17. 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.

P^20

Answer #1

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. .051

Use the standard normal table to find the z-score that
corresponds to the cumulative area 0.7454. 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.
z=_____? (Type an integer or decimal rounded to three decimal
places as needed.)
