Question

An instructor wants to estimate the probability that students in his juniorsenior class have ever cheated in a test during their tenure at the university. To obtain unbiased (truthful) answers from the students, each student is asked to toss a coin privately to answer a decoy question if the outcome is Heads or a real question if the outcome is Tails. The real question is "Did you ever cheat in a test?" and the decoy question is "Are you a graduating senior?" Each student answers "yes" or "no" on a sheet of paper, and the sheets are then collected and tallied by the instructor. Privacy is guaranteed because no one but the individual student knows which question was answered. Of the 35 students participating in the experiment, 20 are graduating seniors. The tallied results of the experiment show 18 yes and 17 no answers. Use this information to estimate the probability that a student in the designated class has ever cheated in a test.
