and releases 19,000 Btu of energy per pound. a) Calculate the cost
of gasoline and electricity for transportation in terms of dollars
per joule. b) Which one is a more costly energy for transportation?
(hint: more costly means cost more for the same amounts of energy)
c) If gas engines are 25% efficient in energy use...

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.
