For the Given Table of Observed Frequencies I) Compute the Row Totals, the Column Totals, and the c

Short Answer

For the given table of observed frequencies:

$\begin{array} { c c c c } \hline & 1 & 2 & 3 \\\hline \mathrm { A } & 60 & 61 & 53 \\\mathrm {~B} & 87 & 90 & 81 \\\mathrm { C } & 41 & 94 & 82 \\\hline\end{array}$

i). Compute the row totals, the column totals, and the grand total.
ii). Construct the corresponding table of expected values.
iii). Compute the value of the chi-square test statistic.
iv). Perform a test for independence, using the $\alpha = 0.05$ level of significance.
