The NTSB wants to estimate the difference between the average stopping distance for a car traveling 40 MPH on wet versus dry pavement.  Ten vehicles were used for the study where each vehicle was driven at 40 MPH and came to a sudden stop on both wet pavement and dry pavement.  The stopping distance was measured (feet) for each pavement condition and the data is shown below followed by Minitab output with the CI.
