1. A researcher claims that 85% of college students would rather spend their extra money for internet access loads than food. Another researcher would like to verify this claim. She randomly selected 450 students. Among them, 269 said that they would rather use their extra money for internet access loads than food. 2. Pedro made a claim that 90% 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 25 out of 40 had joined the race. 3. A certified public accountant (CPA) claims that more than 30% of all accountants advertise. A sample of 112 accountants in Metro Manila showed that 45 use some form of advertising.
