A manufacturer of energy efficient LED light bulbstests competing brands and finds that the amounts of energy they require is normally distributed with a mean of 285 kwh and a standard deviation of 9.1 kwh. In order to get a more realisticpicture of the amount of energy their competitors' light bulbs are actually using they decide to run a second set of tests. However, thelowest 25% and the highest 35% are not going to be includedin the next round of tests. Based on this, what are the upper and lower limits for the energy usage of the light bulbs thatwillbe included in the second round of testing?
