Determine if the finite correction factor should be used. If​ so, use it in your calculations when you find the probability. In a sample of 800 gas​ stations, the mean price for regular gasoline at the pump was $ 2.876 per gallon and the standard deviation was ​$0.008 per gallon. A random sample of size 45 is drawn from this population. What is the probability that the mean price per gallon is less than ​$2.872​? The probability that the mean...

According to an automobile​ association, the average cost of a gallon of regular unleaded fuel at gas stations in a certain month was ​$2.834. Assume that the standard deviation of such costs is ​$0.15. Suppose that a random sample of nequals100 gas stations is selected from the population and the​ month's cost per gallon of regular unleaded fuel is determined for each. What is the approximate probability that the sample has a mean fuel cost between​ $2.84 and​ $2.86? (four...
