Find the indicated z score. The graph depicts the standard normal distribution with mean 0 and standard deviation 1. z 0.8438 A graph with a bell-shaped curve, divided into 2 regions by a line from top to bottom on the right side. The region left of the line is shaded and is labeled 0.8438. The indicated z score is (Round to two decimal places as needed.)
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.0.053Click to view page 1 of the table.
