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 seconds, what would you use for the null hypothesis? μ > 8.7 μ = 8.7 μ ≠8.7 μ < 8.7 (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? μ = 8.7 μ ≠8.7 μ < 8.7 μ > 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? μ > 8.7 μ = 8.7 μ < 8.7 μ ≠8.7 (d) for each of the tests in parts (b) and (c), would the p-value area be on the left, on the right, or on both sides of the mean? both; left left; both right; left left; right
