One-Way ANOVA · Exercise 10
Suppose a group is interested in determining whether teenagers obtain their drivers licenses at approximately the same average age across the country. Suppose that the following data are randomly collected from five teenagers in each region of the country. The numbers represent the age at which teenagers obtained their drivers licenses.
\begin{array}{|c|c|c|c|c|c|}\hline & \text{Northeast} & \text{South} & \text{West} & \text{Central} & \text{East} \\ \hline & \text{16.3} & \text{16.9} & \text{16.4} & \text{16.2} & \text{17.1} \\ \hline & \text{16.1} & \text{16.5} & \text{16.5} & \text{16.6} & \text{17.2} \\ \hline & \text{16.4} & \text{16.4} & \text{16.6} & \text{16.5} & \text{16.6} \\ \hline & \text{16.5} & \text{16.2} & \text{16.1} & \text{16.4} & \text{16.8} \\ \hline \bar{x} = & \text{________} & \text{________} & \text{________} & \text{________} & \text{________} \\ \hline s^{2} = & \text{________} & \text{________} & \text{________} & \text{________} & \text{________} \\ \hline\end{array}
