Question

CNNBC recently reported that the mean annual cost of auto insurance is 1020 dollars. Assume the standard deviation is 260 dollars. You take a simple random sample of 63 auto insurance policies. Find the probability that a single randomly selected value is less than 977 dollars. P(X < 977) = Find the probability that a sample of size n = 63 is randomly selected with a mean less than 977 dollars. P(M < 977) = Enter your answers as numbers accurate to 4 decimal places.
