CNNBC recently reported that the mean annual cost of auto insurance is 972 dollars. Assume the standard deviation is 102 dollars. You will use a simple random sample of 58 auto insurance policies. Find the probability that a single randomly selected policy has a mean value between 977.4 and 997.4 dollars. P(977.4 < X < 997.4) = Find the probability that a random sample of size n=58 has a mean value between 977.4 and 997.4 dollars. P(977.4 < ¯x < 997.4) = Enter your answers as numbers accurate to 4 decimal places.
