Elementary Statistics(10th) Triola Poisson distribution Capter 5-5question 14
Earthquakes:For a recent period of 100 years, there were 93major earthquakes (at least 6.0 on the richter scale) in the world(based on data from the World Almanac and Vook of Facts). Assuming that the Poisson distribution is a suitable model, findthe mean number of major earthquakes per year, then find theprobability that the number of earthquakes in a randomly selectedyear is
A.) 0 B.) 1 C.)2 D.)3 E.)4 F.)5 G.) 6H.) 7
Here are the actual results: 47 years(0 major earthquakes); 31years(1 major earthquake); 13 years( 2 major earthquakes); 5 years(3 major earthquakes); 2 years( 4 major earthquakes); 0 years( 5major earthquakes); 1 year( 6 major earthquakes); 1 year(7 majorearthquakes). After comparing the calculated probabilities to theactual results, is the Poisson distribution a good model?
