Question

In a recent national poll consisting of 1012 randomly selected adults. Participants were asked whether or not human cloning should be allowed. Of those surveyed, 900 indicated human cloning should not be allowed. A newspaper released an article claiming that 90% of those across the nation are against human cloning based on the national poll. Construct a 95% confidence interval estimate for the proportion of adults against human cloning. Does this interval support the newspaper’s claim? Explain. Now, using the information from the previous problem, what sample size would be needed to assure 99% confidence with an error bound of 0.02?
