More than one teacher has given the following advice: choose answerC when blindly guessing among four answers in a multiple choice test, sinceC is more often the correct answer than eitherA,B, orD.


Suppose that we take a random sample of 600 multiple-choice test answers (the correct answers from the instructor's answer sheet) from introductory college courses and obtain the information summarized by the first row of numbers in the table below. These numbers are the observed frequencies for the categories
A,B,C, andD
for our sample of 600 correct answers. The second row of numbers contains thefrequencies expected
for a sample of 600 correct answers if a correct answer is equally likely to beA,B,C, orD. The bottom row of numbers contains the following value for each of the correct answer categoriesA,B,C, andD.
