1. 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 calculate. A. 0.329 to 0.331 B. 0.297 to 0363 C. 0.244 to 0.416 D. 0.324 to 0.336 E. 0.265 to 0.395 2. What proportion of Law School applicants are accepted into Law School? In a survey of a random sample of Law School applicants, the proportion who were accepted into Law School was observed to be 0.44. When a 95% confidence interval was constructed based on this sample of data, it was found to be from 0.40 to 0.48. How should this interval be interpreted? A. If we repeat the sampling process 100 times, 95% of all resulting confidence intervals will be from 0.40 to 0.48. B. We are 95% confident the interval from 0.40 to 0.48 includes the proportion of Law School applicants in this sample who were accepted into Law School. C. We are 95% confident the interval from 0.40 to 0.48 includes the proportion of Law School applicants in the population who are accepted into Law School. D. With 95% confidence, if you apply to Law School, you have a 44% + 4% chance of being accepted. E. In the last 100 years, 95% of all Law School applicants have been accepted into Law School 44% of the time. 3. Which one of the following statements is true? A. The sample proportion is a parameter. B. A confidence interval is computed in order to estimate an unknown sample statistic. C. The margin of error is affected by the size of the sample proportion. D. If you construct a confidence interval for a population proportion and the interval ends up being from 0.48 to 0.59, this means the population proportion is definitely larger than 0.50. E. If a 95% confidence interval is given as 0.32 to 0.46, this means the sample proportion must be 0.38
