A Sociologist Believes That the Levels of Educational Attainment of Homeless

Short Answer

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. Find the critical value χ $$\chi _ { 0 } { } ^ { 2 }$$
to test the
sociologistʹs claim. Use $$\alpha$$ = 0.10. $$\begin{array} { l c } \hline \text { Response } & \text { Frequency, f } \\\hline \text { Less than high school } & 38 \\\text { High school graduate/G.E.D. } & 34 \\\text { More than high school } & 28 \\\hline\end{array}$$
