7.49 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 conditions for the Central Limit Theorem are met, find the probability that at the majority (more than 50%) watched the Super Bowl. (Source: vox.com)

College Enrollment According to data released in 2016, 69% of students in the United
States enroll in college directly after high school graduation. Suppose a sample of 200
recent high school graduates is randomly selected. After verifying the conditions for the
Central Limit Theorem are met, find the probability that at most 65% enrolled in college
directly after high school graduation. (Source: nces.ed.gov)
