Now that you are in college you have already taken a number of standardized exams such as the SAT and ACT exams. A Southern California company that creates standardized exams tries to develop multiple choice questions that are not so difficult that those taking the exams are forced to guess at the answers to most questions. Recently, the company received a complaint about one of the problems on an exam. The problem listed five possible answers. If the test takers were forced to guess, the company might expect an even percentage of choices across the five possible answers. That is, each answer is as likely to be a guess as any other answer. To determine if people were actually forced to guess conduct the appropriate test using a significance level of 0.05.Please be sure to clearly state the null and alternative hypotheses, critical value, test statistic, and conclusion.
