If a histogram of a sample of men's ages is skewed,
what do you expect to see in the normal
quantile plot?
Homework Answers
If the histogram of a sample of men's ages is skewed, Then the normal quantile plot approach normal quantile plots are concave down, and if data are skewed to the left, then normal quantile plots are concave up.
