More than one teacher has given the following advice: choose answer C when blindly guessing among four
answers in a multiple choice test, since C is more often the correct answer than either A, B, or D.
Suppose that we take a random sample of 560 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, and D for our sample of 560 correct answers. The second row of numbers contains the frequencies
expected for a sample of 560 correct answers if a correct answer is equally likely to be A, B, C, or D. The
bottom row of numbers contains the following value for each of the correct answer categories A, B, C, and D.

Answer the following to summarize the test of the hypothesis that each of A, B, C, and D is equally
be the correct answer on tests in these introductory college courses. Use the 0.10 level of significa
test.
(a) Determine the type of test statistic to use.
Type of test statistic: (Choose one)
(b) Find the value of the test statistic. (Round your answer to two or more decimal
places.)
(c) Find the critical value. (Round your answer to two or more decimal places.)
(d) Can we reject the hypothesis that A, B, C, and D are equally likely to be the correct
answer on tests in these introductory college courses?
