Homework Help: statistics

Posted by steve on Wednesday, February 17, 2010 at 1:02am.

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 FAA 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.

1. A commuter plane carries 19 passengers. What is the approximate probability that the total weight of the passengers exceeds 4000 pounds? Use the four-step process and Table A to guide your work.
(Hint: To apply the central limit theorem, restate the problem in terms of the mean weight.)
