Speeds of cars were measured as they passed one point on a road to study whether traffic speed controls were needed. Below are the histogram and normal probability plot of the measured speeds. Is a Normal model appropriate for these? data? Explain.

Choose the correct answer below.

A.

?Yes, the histogram is unimodal and symmetric and the Normal probability plot is straight.

B.

?No, the histogram is skewed to one side and the Normal probability plot is bent.

C.

?Yes, although the histogram is not? unimodal, the Normal probability plot is straight.

D.

?No, the Normal probability plot is very? bent, although the histogram is unimodal and symmetric
