Suppose that the mean time for a certain car to go from 0 to 60 miles per hour was 7.6 seconds. Suppose that you want to set up a statistical test to challenge the claim of 7.6 seconds. What would you use for the null hypothesis?

H₀ : μ > 7.6 seconds

H₀ : μ = 7.6 seconds

H₀ : μ < 7.6 seconds

H₀ : μ ≠ 7.6 seconds

H₀ : μ ≤ 7.6 seconds

Suppose a car dealer tells you that specific cars get 35 miles per gallon on average. You would be able to use hypothesis tests to test whether or not this value might be correct. Why would you use a hypothesis test instead of a confidence interval in this situation? Answer the following questions in a Word document: A car dealer states that a new brand of car gets 35 miles per gallon on average. Suppose a consumer group claims that...

A consumer advocacy group is doing a large study on car rental practices. Among other things, the consumer group would like to do a statistical test regarding the mean monthly mileage, μ, of cars rented in the U.S. this year. The consumer group has reason to believe that the mean monthly mileage of cars rented in the U.S. this year is less than last year's mean, which was 2700 miles. The group plans to do a statistical test regarding the...
