Apply the Chi-Square Test of Homogeneity A $\chi ^ { 2 } = 8.10$

question 6

Short Answer

Apply the Chi-Square test of homogeneity.
-A manufacturing plant for recreational vehicles receives shipments from three different
Parts vendors. There has been a defect issue with some of the electrical wiring in the
Recreational vehicles manufactured at the plant. The plant manager believes that the
Defect issue is dependent on the parts vendor. The plant manager reviews a sample of
Quality assurance inspections from the last six months. The correct value of the test
Statistic for determining if the plant manager's belief is supported is $\begin{array}{|c|c|c|c|}\hline & \begin{array}{c}\text { Perfect Parts } \\\text { Co. }\end{array} & \begin{array}{c}\text { Made-4-U } \\\text { Co. }\end{array} & \begin{array}{c}25 \text { Hour Parts } \\\text { Co. }\end{array} \\\hline \text { Rejected } & 53 & 48 & 70 \\\hline \text { Perfect } & 93 & 71 & 88 \\\hline \begin{array}{c}\text { Not perfect but } \\\text { acceptable }\end{array} & 22 & 31 & 22 \\\hline\end{array}$

A. $\chi ^ { 2 } = 8.10$
B. $\chi ^ { 2 } = 6.52$
C. $\chi ^ { 2 } = 5.03$
D. $\chi ^ { 2 } = 7.40$
E. $\chi ^ { 2 } = 9.89$
