CNNBC recently reported that the mean annual cost of auto insurance is 1002 dollars. Assume the standard deviation is 291 dollars. You take a simple random sample of 72 auto insurance policies. Find the probability that a single randomly selected value is less than 988 dollars. P(X < 988) =  Find the probability that a sample of size n=72n=72 is randomly selected with a mean less than 988 dollars. P(M < 988) =  Enter your answers as numbers accurate to 4 decimal places.
