Goodness-of-Fit Test · Exercise 20
The columns in contain the Race/Ethnicity of U.S. Public Schools for a recent year, the percentages for students using mass transit to get to school, and the Overall Student Population. Suppose the right column contains the result of a survey of 1,000 local students from that year who used mass transit to get to school.
\begin{array}{|c|c|c|c|}\hline \text{Race/Ethnicity} & \text{Percentage Who Use Mass Transit to Get to School} & \text{Overall Student Population} & \text{Survey Frequency} \\ \hline \text{Asian, Asian American, or Pacific Islander} & \text{10.2%} & \text{5.4%} & \text{113} \\ \hline \text{Black or African-American} & \text{8.2%} & \text{14.5%} & \text{94} \\ \hline \text{Hispanic or Latino} & \text{15.5%} & \text{15.9%} & \text{136} \\ \hline \text{American Indian or Alaska Native} & \text{0.6%} & \text{1.2%} & \text{10} \\ \hline \text{White} & \text{59.4%} & \text{61.6%} & \text{604} \\ \hline \text{Not reported/other} & \text{6.1%} & \text{1.4%} & \text{43} \\ \hline\end{array}
Perform a goodness-of-fit test to determine whether the local results follow the distribution of the U.S. overall student population based on ethnicity.
Its source prints no answer for this problem, so there's nothing to check against.
