Quizplus · Accepted Answer

The mean of the number of students who watch the Super Bowl is calculated as the product of the total number of students and the probability of watching the game, which is 200 * 0.5 = 100. The variance is calculated as the product of the total number of students, the probability of watching the game, and the probability of not watching the game, which is 200 * 0.5 * 0.5 = 50. Therefore, the correct answer is Mean = 100.0, Variance = 50.00.
