A 95% confidence interval is constructed for the number of toys that are from china in a random sample of 210 toys. If 70% of all the world's toys come from china,
determine the upper limit, x, of the 95% confidence interval if lower limit is 135.8.
Confidence Interval is given by (135.8, x). Round the value of x (the upper limit
of 95% confidence interval) to 1 decimal place.

Four airplanes carrying a total of 400 passengersarrive at the detroit airport. the airplanes carry, respectively,50, 80, 110, and 160 passengers. a) one of the 400 passengers is selected uniformly at random. let x denote the number of passengers that were on theairplane carrying the randomly selected passenger. find var(x)for x as given in the problemb) one of the 4 airplane drivers is also selected uniformly atrandom. let y denote the number of passengers on the chosen driver’s airplane. find var(y) for y as given in the problem
