Question: Congress regulates corporate fuel economy and sets an annual gas mileage for cars. A company with a large fleet of cars hopes to meet the goal of 30.4 mpg or better for their fleet of cars. To see if the goal is beingmet, they check the gasoline usage for 46 company trips chosen at random, finding a mean of 31.4 mpg and a standard deviation of 2.57 mpg. Is this strong evidence that they have attained their fuel economy goal? Use 0.05 as the level of significance. p-Value = 0.006. State an appropriate conclusion. Choose the correct answer below.

Given: A company with a large fleet of cars hopes to meet the goal of 30.4 mpg or better for their fleet of cars.

That is : Mean = mpg.

Sample size = n = 46

Sample mean =

Sample standard deviation = s = 2.57 mpg

We have to test if there is strong evidence that they have attained their fuel economy goal.

level of significance = 0.05
