Hypothesis testing for proportion

For each problem, conduct a hypothesis testing

14. Surveillance Cameras A research center claims that 63% of U.S. adults support using surveillance cameras in public places. In a random sample of 300 U.S. adults, 70% say that they support using surveillance cameras in public places. At a = 0.05, is there enough evidence to reject the research center's claim? (Adapted from Rasmussen Reports) 15. Dog Ownership A humane society claims that less than 35% of U.S. households own a dog. In a random sample of 400 U.S. households, 156 say they own a dog. At a = 0.10, is there enough evidence to support the society's claim? (Adapted from The Humane Society of the United States) 16. Cat Ownership A humane society claims that 30% of U.S. households own a cat. In a random sample of 200 U.S. households, 72 say they own a cat. At a = 0.05, is there enough evidence to reject the society's claim? (Adapted from The Humane Society of the United States)
