The number of data in age is 10, but there're 9 data in diameter, so they are not in pairs. Suppose we discard one data in age, say 18, then.

age 5, 14, 29, 16, 16, 26, 6, 25, 7,
diameter 8, 23, 34, 24, 24, 10, 30, 14, 13

1. To fit a median-median line to the points, divide the points into three groups. Do this by taking the set of one-third of the points consisting of those with the smallest x-values, a middle group, a set of one-third of the points with the larges x-values. If the number of points is not divisible by three, extra points need to be assigned symmetrically. Thus, if there is one extra point, it should be added to the middle group, and if there are two extra points, add ...
