Question

The national distribution of fatal work injuries in a country is shown in the table to the right under National %. You believe that the distribution of fatal work injuries is different in the western part of the country and randomly select 6231 fatal work injuries occurring in that region. At $alpha = 0.10$ can you conclude that the distribution of fatal work injuries in the west is different from the national distribution? Complete parts a through d below. Which hypothesis is the claim? $H_0$ $H_a$ b. Determine the critical value, $chi^2_0$, and the rejection region. $chi^2_0 = $ (Round to three decimal places as needed.)
