Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.42 and a standard deviation of 1.52. Using the empirical rule, what percentage of American women have shoe sizes that are at least 9.94? Please do not round your answer.

Solutions

Expert Solution

µ = 8.42

                            

                             = P(Z > 1)

                             = 1 - P(Z < 1)

                             = 1 - 0.8413

                             = 0.1587

                             = 15.87%
