CNNBC recently reported that the mean annual cost of auto insurance is 958 dollars. Assume the standard deviation is 150 dollars. You will use a simple random sample of 83 auto insurance policies. Find the probability that a single randomly selected policy has a mean value between 951.4 and 990.9 dollars. P(951.4 < X< 990.9) - Find the probability that a random sample of sizen = dollars. 83 has a mean value between 951.4 and 990.9 P(951.4 < M< 990.9) = Enter your answers as numbers accurate to 4 decimal places.
