Asked by Chris

The scores on the final exam in a course have approximately a bell-shaped distribution. The mean score was 72, the highest score was 99, and the lowest score was 41.

Use the value of the range (58) to estimate the value of the standard deviation. (Round your answer to the nearest tenth.)
