Consider the Accompanying Contingency Table $$\begin{array} { c | c c c } & { \text { Column } } \\\text { Row } & 1 & 2 & 3 \\\hline 1 & 13 & 15 & 16 \\2 & 19 & 26 & 11\end{array}$$

Consider the accompanying contingency table. $$\begin{array} { c | c c c } & { \text { Column } } \\\text { Row } & 1 & 2 & 3 \\\hline 1 & 13 & 15 & 16 \\2 & 19 & 26 & 11\end{array}$$ a. Convert the values in row 1 to percentages by calculating the percentage of each column total falling in row 1. b. Create a bar graph with row 1 percentage on the vertical axis and column number on the horizontal axis. c. What pattern do you expect to see if the rows and columns are not independent? Is this pattern present in your graph? 13.4 A Word of Caution about Chi-Square Tests 1 Understand Assumptions of Chi-Square Tests
