Consumer Reports stated that the mean time for a Chrysler Concorde to go from 0 to 60 miles per was 8.7 seconds. (a) If you want to set up a statistical test to challenge the claim of 8.7 seconds, what would you use for the null hypothesis? Op> 8.7 Op = 8.7 Ou: 8.7 Opc8.7 (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 60 miles per hour is longer in Leadville (because of less oxygen). What would you use for the alternate hypothesis? Op< 8.7 OH= 8.7 Ou* 8.7 Ou> 8.7 (c) Suppose you made an engine modification and you think the average time to accelerate from 0 to 60 miles per hour is reduced. What would you use for the alternate hypothesis? Ομ8.7 Op+ 8.7 Op> 8.7 Op< 8.7 (d) For each of the tests O both; left O left; right parts (b) and (c), would the P-value area be on the left, on the right, or on both sides of the mean? O left; both O right; left
