CNNBC recently reported that the mean annual cost of auto insurance is 1035 dollars. Assume the standard deviation is 250 dollars. You take a simple random sample of 90 auto insurance policies. Find the probability that a single randomly selected value is less than 971 dollars. P(X < 971) = Find the probability that a sample of size n=90n=90 is randomly selected with a mean less than 971 dollars. P(M < 971) = Enter your answers as numbers accurate to 4 decimal places.
