Suppose the Age Distribution of the Canadian Population and the Age

question 8

Multiple Choice

Suppose the age distribution of the Canadian population and the age distribution of a random sample of 447 residents in the Indian community of Red Lake are shown below. 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. State the null and alternate hypotheses.
$$\begin{array} { l l l } \hline \text { Age (years) } & \text { Percent of Canadian Population } & \begin{array} { l } \text { Observed Number } \\\text { in Red Lake Village }\end{array} \\\hline \text { Under } 5 & 7.9 \% & 45 \\5 \text { to } 14 & 13.3 \% & 55 \\15 \text { to } 64 & 65.3 \% & 302 \\65 \text { and older } & 13.5 \% & 45 \\\hline\end{array}$$ $\alpha = 0.1$

• A)The distributions are equal to zero ; The distributions are not the same. \(H _ { 0 } :\) \(H _ { 1 } :\)
• B)The distributions are the same; The distributions are not the same. \(H _ { 0 } :\) \(H _ { 1 } :\)
• C)The distributions are equal to zero; The distributions are the same. \(H _ { 0 } :\) \(H _ { 1 }\)
• D)The distributions are different; The distributions are equal to zero. \(H _ { 0 } :\) \(H _ { 1 }\):
• E)The distributions are not equal to zero; The distributions are not the same. \(H _ { 0 } :\) \(H _ { 1 }\):
