In a nationwide poll of 1000 randomly sampled adults conducted in June 2011, 83% said they think children spend too much time on their computers and other electronic devices (but 37% say time spent on a computer is better than time spent in front of a TV). Find and interpret a 95% confidence interval for the proportion of adults who believe children spend too much time on electronic devices. What is the margin of error for this result? Is it plausible that the proportion of all adults who feel this way is less than 80%? Is it plausible that the proportion is greater than 85%?
