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.

The Toyota Prius is a gasoline-electric hybrid car that gets 54
miles to the gallon. An article in the Wall Street Journal notes
that sales of the Prius have been hurt by low gasoline prices and
that: "Americans are now more likely to trade in a hybrid or an
electric vehicle for an SUV...."
Does the article indicate that gasoline-powered cars and
gasoline are substitutes or complements? Briefly explain.
A.
Substitutes, because the more consumers buy of one good, the...

The data provided give the gasoline mileage (in miles per
gallon) based on the horsepower of a car's engine and the weight
of the car (in pounds). Using the data provided, determine the
VIF for each independent variable in the model. Is there reason to
suspect the existence of collinearity?
Determine the VIF for each independent variable in the
model.

Suppose gas costs $3 a gallon and the average car gets 28 miles
per gallon. If Congress mandates that cars have to get 36 miles per
gallon, by what percentage will this lower the costs of driving? If
the elasticity of total miles driven (per year) with respect to the
cost of driving is –1, by how much will total miles driven per year
increase, assuming it is 10,000 miles at the beginning? How much
will total annual gas consumption...
