9. Solve the problems. Use the graph for the standard deviation points. In a fishing contest, the length of the fish caught ranged from 11.5 inches to 23 inches with a mean length of 16.40 inches and
standard deviation of 4.71 inches. Assume there was a normal distribution. What percent of the fish caught would have a length
greater than 21.11 inches, one standard deviation above the mean?
