Shown Below Is 2 X 3 Contingency Table with Observed

Short Answer

Shown below is 2 x 3 contingency table with observed values from a sample of 500. At 95% confidence using the critical value approach, test for independence of the row and column factors.
Column Factor
$\begin{array}{|l|c|c|c|}\hline \text { Row Factor } & \mathrm{X} & \mathrm{Y} & \mathrm{Z} \\\hline \mathrm{A} & 40 & 50 & 110 \\\hline \mathrm{B} & 60 & 100 & 140 \\\hline\end{array}$ $\begin{array}{|l|c|c|c|}\hline \text { Row Factor } & \mathrm{X} & \mathrm{Y} & \mathrm{Z} \\\hline \mathrm{A} & 40 & 50 & 110 \\\hline \mathrm{B} & 60 & 100 & 140 \\\hline\end{array}$
