ain magazine stated that the mean time for a Ford Mustang to go from 0 to 60 miles per hour is 4.7 seconds. If you want to set up a statistical test to challenge the claim of 4.7 seconds, what would you use for the null hypothesis? = 4.7 μ*4.7 μ> 4.7 O μ< 4.7 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> 4.7 O μ* 4.7 O μ< 4.7 O μ = 4.7 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? Oμ* 4.7 O μ< 4.7 Oμ> 4.7 OH = 4.7 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?

Question
A certain magazine stated that the mean time for a Ford Mustang to go from 0 to 60 miles per hour is 4.7 seconds. (a) If you want to set up a statistical test to challenge the claim of 4.7 seconds, what would you use for the null hypothesis? O μ = 4.7 Oμ 4.7 O μ> 4.7 O μ< 4.7 (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? Ο μ > 4.7 Oμ 4.7 Ο μ < 4.7 Ο μ = 4.7 (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? O μ # 4.7 Ο μ < 4,7 0μ > 4.7 OH = 4.7 (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?
