Chrysler Concorde: AccelerationConsumer reports stated that the mean time for a ChryslerConcorde to go from 0 to 60 miles per hour was 8.7 seconds.
a.) If you want to set up astatistical test to challenge the claim of 8.7 seconds, what wouldyou use for the null hypothesis?
b.) The town of Leadville, Colorado,has an elevation over 10,000 feet. Suppose you wanted to test theclaim that the average time to accelerate from 0 to 60 miles perhour is longer in Leadville (because of less oxygen). What wouldyou use as an alternative hypothesis?
c.) Suppose a newer model yearChrysler Concorde came out and you wanted to test whether theaverage time to accelerate from 0 to 60 miles per hour had changedfrom the previous year. What would you use as an alternativehypothesis?
d.) Suppose you made an enginemodification and you think the average time to accelerate from 0 to60 miles per hour is reduced. What would you use as an alternativehypothesis?
e.) For each of the tests in parts(b), (c), and (d) , would the P-value area be on the left, on theright, or on both sides of the mean?
