Mario made a claim that 95% of college male students in their school join triathlon. His friend, Baste, finds this hard to believe and decided to check the validity of such claim, so he took a random sample and found out that 75 out of 90 had joined the race. 1. What is the population proportion? 2. What is the sample proportion? 3. Is the sample large enough to use the Central Limit Theorem?
