The distributions for the 5-kilometer race and 20-kilometer race are both symmetric, and there are no outliers. The times for the 5-kilometer race peak between 1717 and 1818 minutes, while the times for the 20-kilometer race peak between 7171 and 7575 minutes. The distribution for the 5-kilometer race is roughly symmetric, and the distribution for the 20-kilometer race is skewed right.

Nicole is interested in horses, and she reads some interesting tidbits of information about them. For example, did you know that the most common color of a horse is “bay.” This means they have brown bodies with a black mane, tail, and lower legs, like the horse pictured to the right. Nicole also reads that the length of horse pregnancies from conception to birth have an average (mean) of about 340 days with a standard deviation of 12.2 days.
