CNNBC recently reported that the mean annual cost of auto insurance is 1018 dollars. Assume the standard deviation is 139 dollars. You will use a simple random sample of 56 auto insurance policies. Find the probability that a single randomly selected policy has a mean value between 967.8 and 1058.9 dollars. P(967.8 < X < 1058.9) = Find the probability that a random sample of size n=56=56 has a mean value between 967.8 and 1058.9 dollars. P(967.8 < M < 1058.9) =
