In determining automobile mileage ratings, it was found that the mpg in the city for a certain model is normally distributed, with a mean of 30 mpg and a standard deviation of 1.7 mpg. Suppose that the car manufacturer samples four cars from its assembly line and tests them formileage ratingsa. What is the distribution of the mean mpg for the sample?b. What is the probability that the mean mpg of the sample will be greater than 31 mpg?c. What is the probability that the mean mpg of the sample will be less than 28.5 mpg?UDa. What is the distribution of the mean mpg for the sample? Select the correct choice below and fill in the answer boxes to complete your choice.(Type integers or decimals rounded to two decimal places as needed.)OA. The sampling distribution of the mean follows a normal distribution with the sample meanOB. The sampling distribution of the mean follows a triangular distribution with the sample meanOC. The sampling distribution of the mean follows a uniform distribution with the sample meanOD. The sampling distribution of the mean follows an exponential distribution with the sample meanmpg and the standard deviation of the sample meanmpg and the standard deviation of the sample meanmpg and the standard deviation of the sample meanmpg and the standard deviation of the sample meanmpgmpg.mpgmpg
