Using Probability to Identify Unlikely Events.
Chapter 4, Problem 32(choose chapter or problem)
Using Probability to Identify Unlikely Events. In Exercises 2936, consider anevent to be unlikely if its probability is less than or equal to 0.05. (This is equivalentto the same criterion commonly used in inferential statistics, but the value of 0.05 is notabsolutely rigid, and other values such as 0.01 are sometimes used instead.) Air Travel Fatalities One measure of air travel safety is this: There are 117 fatalitiesper billion passenger flights. Express that measure as a probability. Is it unlikely for an air passengerto be a fatality? How does air travel compare to the car fatality rate of 40 fatalities perbillion trips? Is this comparison fair?
