Super Bowl: In 2018 it was estimated that approximately 45% of the American population watches the Super Bowl yearly. Suppose a sample of 120 Americans is randomly selected. After verifying the condition for the Central Limit Theorem are met, find the probability that a majority (more than 50%) watched the super Bowl. Verify that the conditions for the Central Limit Theorem for Sample Proportions have been met: (met or not met) 1) Random and Independent: Is the sample collected randomly and the trials are independent from each other? (met or not met) 2) Large Sample: Is there at least 10 successes and at least 10 failures? (met or not met)
