Question
In response to the increasing weight of airline passengers, the Federal Aviation Administration (FFA) told airlines to assume that passengers average 190 lbs 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 lbs. 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 36 passengers.
a) What is the approximate probability that the total weight og the passengers exceeds 7,500 lbs? (Carry your anser to 4 decimal places, if necessary. HINT: To apply the Central Limit Theorem, restate the problem in terms of the average weight.)
