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.

Step-by-step explanation:

The answer is C, the type of vehicle is a confounding variable.

what do you mean by fog

step-by-step explanation:

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
