suppose a statistics exam consists of 30 True-False questions. If you randomly guess at every question, how ikely are you to pass the exam with at least 70% (21 correct answers)? o answer this question, go to the Rossman/Chance applet titled "Simulation-Based and Exact One Proportion Inference ." Use the Rossman/Chance applet with at least 5000 simulations to estimate the probability. What is the approximate probability that you correctly guess at least 21 correct answers?
