Suppose that the mean time for a certain car to go from 0 to 60 miles...

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....

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...

The maker of a certain model car claimed that the car averaged at least 36 miles per gallon of gasoline. A sample of nine cars was selected and each car was driven with one gallon of regular gasoline. The sample showed a mean of 34.43 miles with a standard deviation of 3 miles. Assume you doubt that the car can achieve 36 miles per gallon - you believe the fuel efficiency would actually be lower. State your hypothesis and test...
