Cat and dog owners. In April 2007, the Gallup Poll asked a random sample of 1007 adults, “Thinking of your own situation, do you personally own a cat, a dog, both, or neither?” It found that 59% said they owned a cat, a dog, or both. Suppose that the sample size had been 4000 rather than 1007. Find the margin of error for 95% confidence in this case. How does it compare with the margin of error for a sample of size 1007?
