CNNBC recently reported that the mean annual cost of auto insurance is 999 dollars. Assume the standard deviation is 227 dollars. You take a simple random sample of 76 auto insurance policies. Find the probability that a single randomly selected value is less than 963 dollars. P(X < 963) = Find the probability that a sample of size n=76n=76 is randomly selected with a mean less than 963 dollars. P(M < 963) =
