The average gas mileage of a certain model car is 28.0 miles per gallon. If the gas mileages are normally distributed with a standard deviation of 0.4 miles per gallon, find the probability that a car has a gas mileage of between 26.8 and 27.2 miles per gallon.   In addition to the answer, please write out your steps and thoughts that led you to your answer.

Currently, a manager is using a regression model that predicts gas mileage​ (in miles per​ gallon) based on the horsepower of a car and the​ car's weight​ (in pounds). She believes that the effect of HP on gas milage is affected by the weight and vice versa. Develop a regression model that includes​ horsepower, weight, and this new interaction effect to predict gas mileage. Complete parts​ (a) and​ (b).

The corporate average fuel economy​ (CAFE) standard for mileage is currently 28 miles per gallon of gasoline​ (the defender) for passenger cars. To conserve fuel and reduce air​ pollution, suppose the U.S. Congress sets the CAFE standard at 35 miles per gallon​(the challenger) in 2010. An auto will emit on average 0.8 pounds of carbon dioxide ​(CO2​) per mile driven at 28 miles per​ gallon, and it will emit 0.7 pounds of O2 per mile driven at 35 miles per...
