RA company that manufactures car tires wants to compare breaking performance on dry and wet pavements for a brand of their tires. They selected a random sample of 10 sets of tires and put them on 10 cars. The stopping distance (ft) on dry pavement and wet pavement was recoded for each car. The results are summarized in the table below.
