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 offatal work injuries is different in the western part of the country and randomly select 6231 fatal work injuries occuring in that region. At a = 0.05can you conclude that the distribution of fatal work injuries in the west is different from the national distribution? Complete parts a through d below.

Chi - square The age distribution of the population in Canada consists of 7.2% inhabitants of ages from 5 years old and below, 13.6% of inhabitants of ages between 6 and 14, 67.1% of inhabitants of ages between 15 and 64, and 12.1% of inhabitants of ages from 65 and above. Lately in a survey conducted on 455 residents in a native-Canadian village in the Northwest Territories (Red Lake Village), it has been counted that there are 47 children with the age of 5 or below, 75 persons with ages between 5 and 14, 288 persons with ages between 15 and 64, and 45 persons with ages of 65 years and above. a)use descriptive statistics for presenting the data b)Use a 5% level of significance to test if there is an agreement between the age distribution in Canada and the age distribution of the residents of Red Lake Village.
