A car company says that the mean gas mileage for its luxury sedan is at least 23 miles per gallon (mpg). You believe the claim is incorrect and find that a random sample of 6 cars has a mean gas mileage of 22 mpg and a standard deviation of 5 mpg. At a=0.05, test the company's claim. Assume the population is normally distributed. Click here to view the t-distribution table. Click here to view page 1 of the normal table. Click here to view page 2 of the normal table. Which sampling distribution should be used and why? OA. Use a t-sampling distribution because the population is normal, and a is unknown. OC. Use a normal sampling distribution because n> 30. OE. Use a normal sampling distribution because the population is normal, and a is known. B. Use a t-sampling distribution because n<30. D. Use a normal sampling distribution because the population is normal, and a is unknown. OF. Use a t-sampling distribution because the population is normal, and a is known.
