Question

The environmental protection agency rates the mean highway gas mileage of the 2013 Ford Edge to be 27 miles per gallon. Assume the standard deviation is 3 miles per gallon. Rental car company buys 60 of these car. 
a) commute the mean(ux) and the standard deviation (ox) of x. Round to 4 decimal places)

b) what is the probability that the average mileage of the fleet is greater than 26.5 miles per gallon? (Make sure the normal curve with shaded area) 

c) what is the probability that the average mileage of the fleet is between 26 and 26.8 miles per gallon? (Make sure to draw the normal curve with the shaded area)
