Question: Hypothesis Testing

Chrysler Concorde: Acceleration Consumer Reports stated that the mean time for a Chrysler Concorde to go from 0 to 60 miles per hour was 8.7 seconds.

a. If you want to set up a statistical test to challenge the claim of 8.7 second, what would you use for the null hypothesis?

b. 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 60miles per hour is longer in Leadville (because of less oxygen).What would you use for the alternate hypothesis?

c. Suppose you made and engine modification and you think that the average time to accelerate from 0 to 60 miles per hours has been reduced .What would you use for the alternate hypothesis?

d. State your conclusion in the context of the application.
