The number of miles a motorcycle, X, will travel on one gallon of gasoline is modeled by a normal distribution with mean 44 and standard deviation 5. If Mike starts a journey with one gallon of gasoline in the motorcycle, find the probability that, without refueling, he can travel more than 50 miles.

Suppose that you are interested in estimating the average number
of miles per gallon of gasoline your car can get. You calculate the
miles per gallon for each of the next twenty-five times you fill
the tank. Suppose that in truth, the values for your car are
bell-shaped, with a mean of 20 miles per gallon and a standard
deviation of 1. Find the possible sample means you are likely to
get based on your sample of twenty-five observations. Consider...

A research firm tests the miles-per-gallon characteristics of
three brands of gasoline. Because of different gasoline performance
characteristics in different brands of automobiles, five brands of
automobiles are selected and treated as blocks in the experiment;
that is, each brand of automobile is tested with each type of
gasoline. The results of the experiment (in miles per gallon)
follow.

Though the electric-gasoline engine allows better miles per
gallon relative to a traditional gasoline engine, it is not without
technological tradeoffs. Regarding the first electric-gasoline cars
to market, much of the mpg achieved was due to styling not the
ability to run on electricity, which from market surveys not as
appealing as the styling of a sleeker vehicle body design. New and
limited infrastructure for servicing these vehicles was created,
which may have deterred buyer acceptance.

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 manufacturer of a new compact car claims the miles per
gallon (mpg) for the gasoline consumption is mound-shaped and
symmetric with a mean of 27.4 mpg and a standard deviation of 12.3
mpg. If 30 such cars are tested, what is the probability the
average mpg achieved by these 30 cars will be greater than 28?

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.

Volkswagen sells the "Golf" in both gasoline-powered and
electric-powered versions. The gasoline Golf gets 37 miles/gallon
and the electric e-Golf gets 3.42 miles/kWh. Assume the average
person drives 12,000 miles per year.
a) What are the annual emissions in kg CO2 for driving the Golf
and e-Golf? For gasoline, assume that it emits 8,165 g CO2 per
gallon of gasoline. For electricity, use the table below to
determine greenhouse gas emissions.
