1) The owner of a local gas station would like to estimate the mean number of gallons sold to his customers. Assume that the number of gallons sold follow a normal distribution with a population standard deviation 0f 2.5 gallons. He selects a random sample of 100 sales and finds the mean number of gallons sold equals 9.2 What is...

Find the probability and interpret the results. If convenient, use technology to find the probability. During a certain week the mean price of gasoline was $2 717 per gallon. A random sample of 38 gas stations is drawn from this population. What is the probability that the mean price for the sample was between S2 699 and S2 718 that...
