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
