Suppose the Age Distribution of the Canadian Population and the Age

Suppose the age distribution of the Canadian population and the age distribution of a random sample of 531 residents in the Indian community of Red Lake are shown below. $$\begin{array} { l l l } & & \text { Observed Number } \\\text { Age (years) } & \text { Percent of Canadian Population } & \text { in Red Lake Village } \\\hline \text { Under } 5 & 8.9 \% & 49 \\5 \text { to } 14 & 11.9 \% & 41 \\15 \text { to } 64 & 67.8 \% & 389 \\65 \text { and older } & 11.4 \% & 52 \\\hline\end{array}$$ Use to test the claim that the age distribution of the general Canadian population fits the age distribution of the residents of Red Lake Village.
