a pollster wants to construct 95% confidence interval for the proportion of adults who believe that economic conditions are getting better. A gallup poll taken in July 2010 estimates this proportion to be 0.33. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.016?
