Questions: Find the indicated z score. The graph depicts the standard normal distribution with mean 0 and standard deviation 1. The indicated z score is 66 . (Round to two decimal places as needed.)

Solution Steps

The problem requires finding the z-score for a given area under the standard normal distribution curve. The area to the right of the z-score is 0.2546.

Since the total area under the standard normal distribution curve is 1, the area to the left of the z-score is: \[ 1 - 0.2546 = 0.7454 \]

Using the z-table, find the z-score that corresponds to an area of 0.7454 to the left of the z-score. The z-score that corresponds to an area of 0.7454 is approximately 0.66.
