Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.11 and a standard deviation of 1.46 Using the empirical rule, what percentage of American women have shoe sizes that are at least 11.03? Please do not round your answer.

Step 1

Consider,

*X* be a random variable that represents the shoe size of American women that has a bell-shaded distribution.

Mean (µ) = 8.11

Standard deviation (σ) =1.46

Step 2

Thus,

Step 3

Hence, the percentage of shoe size that are at lea...
