The proportion of people that own cats is 20%. A veterinarian believes that this proportion is smaller than 20% and surveys 100 people. Test the veterinarian's claim at the a = 0.01 significance level. Preliminary: a. Is it safe to assume that n ≤ 0.05 of all subjects in the population? O Yes O No b. Verify np(1 - p) ≥ 10. Round your answer to one decimal place.
