A metropolitan transportation authority has set a bus mechanical reliability goal of 3,900 bus miles. Bus mechanical reliability is measured specifically as the number of bus miles between mechanical road calls. Suppose a sample of 100 buses resulted in a sample mean of 3,950 bus miles and a sample standard deviation of 225 bus miles.   Determine the​ p-value and interpret its meaning.   The​ p-value is ________ ​(Round to three decimal places as​ needed.)       A. The​ p-value is the probability of getting a sample mean of 3,950 bus miles or greater if the actual mean is 3,900 bus miles.   B. The​ p-value is the probability that the actual mean is 3,950 bus miles or less.   C. The​ p-value is the probability that the actual mean is greater than 3,950 bus miles.   D. The​ p-value is the probability that the actual mean is 3,900 bus miles or greater given the sample mean is 3,950 bus miles.
