In response to the increasing weight of airline passengers, the Federal Aviation Administration (FAA) in 2003 told airlines toassume that passengers average 195 pounds in the winter, including clothing and carry-on baggage. But passengers vary, and theFAA did not specify a standard deviation. A reasonable standard deviation is 35 pounds. Weights are not normally distributed,especially when the population includes both men and women, but they are not very non-Normal.A commuter plane carries 22 passengers. What is the approximate probability that the total weight of the passengers exceeds4500 pounds? Use the four-step process to guide your work. Give your answer as a percentage precise to two decimal places.You may find Table A useful.2.56probability:Incorrect4:39
