(5) (a) A study is made to determine the proportion of voters in a sizable community who favor the construction of a chemical plant. If 240 of 800 voters selected at random favor the project and we used p = 240/800 = 0.30 as an estimate of the actual proportion of all votors in the community who favor the project, what can we say with 99% confidence about the maximum error?
