question 54

Essay

A sociologist believes that the levels of educational attainment of homeless persons are not uniformly
distributed. To test this claim, you randomly survey 100 homeless persons and record the educational
attainment of each. The results are shown in the following table. At α $$\alpha$$ = 0.10, is there evidence to support the
sociologistʹs claim that the distribution is not uniform? $$\begin{array} { l c } \hline \text { Response } & \text { Frequency, } \mathrm { f } \\\hline \text { Less than high school } & 38 \\\text { High school graduate/G.E.D. } & 34 \\\text { More than high school } & 28 \\\hline\end{array}$$
