a printer manufacturing company claims that its new ink-efficient printer can print an average of 1600 pages of word documents with standard deviation of 62. thirty-five of those printers showed a mean of 1585 pages. does this support the company’s claim? use 95% confidence level.
an airplane is flying at an altitude of 6000m over the ocean directly toward a coastline. at a certain time the angle of depression to the coastline from the airplane is 14 degrees. how much farther does the airplane have to fly before it is directly over the coastline
