CNNBC recently reported that the mean annual cost of auto insurance is 1017 dollars. Assume the standard deviation is 113 dollars. You will use a simple random sample of 147 auto insurance policies. You may assume original population is approximatley normally distributed, and round your answers to three decimals. Find the probability that a single randomly selected policy has a mean value between 999.3 and 1019.8 dollars. Find the probablitty that a random sample of n=147 has a mean value between 999.3 amd 1019.8 dollars
