Mathematics
In response to the increasing weight of airline passengers, the Federal Aviation Administration in 2003 told airlines to assume that passengers average 190 pounds in the summer, including clothing and carry-on baggage. But passengers vary, and the FFA 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. With the approximate probability P that the total weight of the passengers exceeds 4500 pounds? Use the four-step process to guide your work.
