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 38.7 mpg or better for their fleet of cars. To see if the goal is being met, they check the gasoline usage for 41 company trips chosen at random, finding a mean of 41.70 mpg and a standard deviation of 4.93 mpg. Is this strong evidence that they have attained their fuel economy goal? Use 0.05 as the P-value cutoff level. Also find P-Value.
