CNNBC recently reported that the mean annual cost of auto insurance is 1008 dollars. Assume the standard deviation is 299 dollars. You take a simple random sample of 58 auto insurance policies.
Find the probability that a single randomly selected value is more than 961 dollars. P(X > 961) =
Find the probability that a sample of size n = 58 is randomly selected with a mean that is more than 961 dollars. P(M > 961) =
