The data below were collected to determine if there were the same number of hurricanes during 10 year periods across time. The data was collected to count the numbers of large (category 3.4 or 5) hurricanes that struck the US. The critical value for this test is 11.07. Years Count 8 7 8 1891-1900 1911-1920 1931-1940 1951-1960 1971-1980 1991-2000 9 4. 5

J What is the null hypothesis for the test in question 12? The number of hurricanes per 10 year period matches the expected distribution There is a relationship between the 10 year periods and the number of hurricanes There number of hurricanes and 10 year period are independent The number of hurricanes per 10 year period does not match the expected distribution
