  1. The Environmental Protection Agency rates the mean highway gas mileage of the 2017 Chevrolet Sonic to be 28 miles per gallon. Assume the standard deviation is 3 miles per gallon. A rental car company buys 50 of these cars.
    1. What is the probability that the mean gas mileage of the rental fleet is less than 27.5 miles per gallon?
    2. Find the 70th percentile of the mean mileage for the rental fleet. Round your answer to two decimal digits.

The Environmental Protection Agency measures a mean gas mileage for recently tested cars as 24.8 mpg with a standard deviation of 6.2 mpg. The dataset on Fuel economy in StatCrunch gives an average of 24.2 mpg with a standard deviation of 6.5 mpg. Joe’s car is estimated at 30 mpg.

In its Fuel Economy Guide for 2014 model vehicles, the Environmental Protection Agency gives data on 1160 vehicles. There are a number of high outliers, mainly hybrid gas-electric vehicles. If we ignore the vehicles identified as outliers, however, the combined city and highway gas mileage of the other 1134 vehicles is approximately Normal with mean 22.8 miles per gallon (mpg) and standard deviation 5.3 mpg. The quintiles of any distribution are the values with cumulative proportions 0.20, 0.40, 0.60, and...

We expect a car's highway gas mileage to be related to its city gas mileage (in miles per gallon, mpg). Data for all 1137 vehicles in the government's Fuel Economy Guide give the regression line highway mpg = 6.785 + (1.033 * city mpg) for predicting highway mileage from city mileage. (a) What is the slope of this line? (Enter your answer to three decimal places.) mpg Say in words what the numerical value of the slope tells us. Highway...
