Solution Summary

This solution discusses variables that are normally distributed.

Solution Preview

a. Shoe size of adult males.
I would expect this not to be normally distributed because shoe sizes are discrete numbers, for example, 8, 8.5, 9, 9.5 etc., whereas the normal distribution is continuous.

b. Years of education of 30-year-old employed women.
I ...
