Suppose I gave my statistics class a four-question, multiple-choice quiz at the beginning of the semester to measure how well prepared they were for the class. The following table shows the number of students who had 0, 1, 2, 3, and 4 questions correct:

Number of Correct Answers per Student Frequency 0 4 1 5 2 12 3 9 4 10 Total 40 Using a = 0.05, perform a chi-square test to determine if the number of correct answers per student follows the binomial probability distribution.
