3. Consumer Reports indicated that the mean braking distance (from 60 miles per hour) on wet pavement for the Mercury Sable was 159 feet. Suppose that Sables equipped with tires having a new tread designed to grip the road better on wet pavement are used in 45 tests. The sample mean braking distance was 150 feet with sample standard deviation of 26.5 feet. Does this information indicate that the mean braking distance for Mercury Sables on wet pavement is reduced for the new tire tread? Use a=.05 level of significance. Step 1: State Hypotheses (make sure you use the right symbol, the right signs for this problem, and have the right numerical value for the hypothesis) Ho: H₁:
