The American Academy of Pediatrics offers guidelines and recommendations for how much “screen time” (i.e., time in front of the television or other electronic devices) young children should have. One recommendation is that children between the ages of 2 and 5 years should have no more than two hours of screen time per day. What proportion of parents of young children follow these recommendations? To estimate this parameter, a pediatrician surveys 200 randomly selected parents of children between the ages of 2 and 5 years. The proportion of these parents who indicate they follow screen time recommendations for their children is 0.33. Use this information to construct a 99% confidence in order to estimate the population proportion of all parents of children between the ages of 2 and 5 years who follow screen time recommendations. As you construct the interval, round your margin of error to three decimal places as you are engaging in calculations, and choose the answer below that is closest to what you ca
