Motor Trend stated that the mean time for a Ford Mustang to go from 0 to 60 miles per hour is 4.4 seconds. The town of Leadville, Colorado, has an elevation over 10,000 feet. Suppose you wanted to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer in Leadville (because of less oxygen). State the null and alternative hypotheses of a test to determine if the average time of acceleration is longer in Leadville.
