Question

The age distribution of the Canadian population and the age distribution of a random sample of 454 residents in the Indian community of Red Lake Village (Northwest Territories) are shown below (based on U.S. Bureau of the Census, International Database). It is claimed that the age distribution of the general Canadian population fits the age distribution of the residents of Red Lake Village, that is all population proportions are as well true in the Red Lake Village population.

Age (years) Percent of Canadian population Observed number in Red Lake Village
Under 5 7.2 % 47
5 to 14 13.8 % 76
15 to 64 67.2 % 287
65 and older 11.8 % 44



A) The sample has degree of freedom:

��= 

B) The expected count of the age Under 5 is:

�=  . DO NOT round your answer

C) Accurate to 2 decimal places, the component value of the age Under 5 is:

component= 

D) �2 value of this sample is:

�2= 

E) At significance level 0.05, is the sample showing strong evidence to reject the claim? Use 4 decimal places for �-value.

  • Yes
  • No



F) The �-value for this sample was:
