here is a population of millions of computer chips produced at a factory. The production process is so precise that it is known that the population standard deviation for their mass is 2 milligrams. We want to get a 95% confidence interval for the mass of a single microchip produced here. So we randomly sample 100 microchips. The sample average mass turns out to be 1972 milligrams. They found this by placing them all on a scale at once and finding a mass of 197.2 grams, and then dividing by 100. You don't think they would actually weigh each one individually, do you? That would be super annoying. Find a 95% confidence interval for the mass of a microchip produced at this factory. Enter the UPPER bound below, rounded to the nearest tenth of a milligram.
