- Please do not give solution in image format thanku Do our children spend enough time enjoying the outdoors and playing with friends, or are they spending more time glued to the television, computer, and their cell phones? 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.)Show complete solutionThere is a 95% chance of passing any exam. What is mean in number of attempts until third exam is passed?Is the average time to complete an obstacle course longer when a patch is placed over the right eye than when a patch is placed over the left eye? Eight randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.
