CNNBC recently reported that the mean annual cost of auto insurance is 1020 dollars. Assume the standard deviation is 247 dollars. You take a simple random sample of 68 auto insurance policies. Find the probability that a single randomly selected value is less than 975 dollars. P(X < 975) = Find the probability that a sample of size n=68n=68 is randomly selected with a mean less than 975 dollars. P(M < 975) = around to four places
