Question 3 Suppose that the height, in inches, of a 22-year-old man is a normal random variable with mean 71 and variance 6.25. 1. What percentage of 22-year-old man are over 74 inches tall? 2. What percentage of 22-year-old men in the 72-inch club (no one below 72 inches) are over 77 inches? 3. There are ten 22-year-old men in the 72-inch club. What’s the probability that more than 8 of them are over 74 inches?(You can write down the answer with scientific notation) 4. For the last question, what assumptions are you making?
