The National Hurricane Center provides data that list the number of large (category 3, 4, or 5)
hurricanes that have struck the United States, by decade since 1851. The data is stored in
Stat42190-01Test4Q15Data.csv
Recently there has been some concern that perhaps the number of large hurricanes has been
increasing. The natural hypothesis would be that the frequency of such hurricanes has
remained constant.
1. With 109 large hurricanes observed over the 17 periods, what are the expected values for
each cell?
2. What kind of chi-square test would be appropriate?
3. State the null and alternative hypothesis
4. How many degrees of freedom are there?
5. What is the value of the test statistic?
6. What is the P-value?
7. State the conclusion?
