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 8.6 seconds. Suppose that you want to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer than 8.6 seconds. What would you use for the alternative hypothesis?

Group of answer choices

H₁ : μ < 8.6 seconds

H₁ : μ = 8.6 seconds

H₁ : μ ≤ 8.6 seconds

H₁ : μ > 8.6 seconds

H₁ : μ ≥ 8.6 seconds

Answer 1

Answer #1

solution:

this is the right tailed test .

The null and alternative hypothesis is ,

H0 : = 8.6

H1 : >8.6

alternative hypothesis is H1 : >8.6

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...
