Highway paint data

A state highway department uses two brands of paint for painting stripes on roads. A highway official wants to know whether the durability of the two brands of paint are different. For each paint, the official records the number of months the paint persists on the highway.

You can use this data to demonstrate Mann-Whitney Test and other analyses that compare population medians.
