You are interested in determining which of two brands of windshield wipers, brand A and brand B, lasts longer under
differing conditions of use. One hundred Toyota Highlanders are fitted with brand A wipers and 100 Chevrolet
Equinoxes are fitted with brand B wipers. Each pair of wipers is used for two years. Wiper wear is then measured for
each pair of wipers, and the average windshield wiper wear for the two brands is compared. What is wrong with this
experimental design?
Nothing is wrong with this design.
Not enough windshield wipers of each type are used in the study.
The type of vehicle is a confounding variable.
The experiment should have been conducted on more than two brands of vehicles.
