Braking test A tire manufacturer tested the braking per-formance of one of its tire models on a test track. The company tried the tires on 10 different cars, recording the stopping distance for each car on both wet and dry pave-ment. Results are shown in the table.a) Write a 95% confidence interval for the mean drypavement stopping distance. Be sure to check theappropriate assumptions and conditions, and explainwhat your interval means.b) Write a 95% confidence interval for the mean increasein stopping distance on wet pavement. Be sure tocheck the appropriate assumptions and conditions, andexplain what your interval means.
