A random sample of 250 youth between the ages of 8 and 18 showed that 160 of them had a TV in their bedroom and that 90 had a video game console in their bedroom. Estimate the proportion of all 8- to 18-year-olds who have a TV in their bedroom and calculate the 95% margin of error for your estimate. (Round your margin of error to three decimal places.)

Round using 3 decimal places and enter percentages as numbers between 0 and 1 (e.g., if result is 53.478% enter 0.535) Use the variable metacritic (the metacritic critic score) from data-frame fandango (need to obtain from package fivethrityeight) b) Using the actual data, what is the percentage of metacritic critic scores that are greater than 70 and less than or equal to 95?
