Question: The serum cholesterol levels in men aged 18~24 are normally distributed with a mean of 178.1 and a standard deviation of 40.7 . Units are in mg/100mL, and the data is based on the National Health Survey.

1. If one man aged 18-24 is randomly selected, find the probability that his serum cholesterol level is greater than 260, a value considered "moderately high."
2. If one man aged 18-24 is randomly selected, find the probability that his serum cholesterol level is between 170 and 200.
3. If nine men aged 18-24 are randomly selected, find the probability that their serum cholesterol level is between 170 and 200.
4. The Providence Health Maintenance Organization wants to establish a criterion for recommending dietary changes if cholesterol levels are in the top 3%. What is the cutoff for men aged 18-24?
