The conditional relative frequency table below was generated by column from a frequency table comparing the color of a flower to a type of flower.

\begin{tabular}{|c|c|c|c|}
\cline { 2 - 4 } \multicolumn{1}{c|}{} & Daisy & Rose & Total \\
\hline Red & A & B & C \\
\hline Yellow & [tex]$D$[/tex] & [tex]$E$[/tex] & [tex]$F$[/tex] \\
\hline White & G & [tex]$H$[/tex] & [tex]$J$[/tex] \\
\hline Total & 1.0 & 1.0 & 1.0 \\
\hline
\end{tabular}

Which would most likely indicate an association between the categorical variables?

A. The value of [tex]$G$[/tex] is similar to the value of [tex]$H$[/tex].
B. The value of [tex]$B$[/tex] is similar to the value of [tex]$E$[/tex].
C. The value of [tex]$G$[/tex] is not similar to the value of [tex]$H$[/tex].
D. The value of [tex]$B$[/tex] is not similar to the value of [tex]$E$[/tex].


Sagot :

To determine an association between the categories in the given conditional relative frequency table, we can analyze the similarities between the values.

Here is the filled table with hypothetical values:

[tex]\[ \begin{tabular}{|c|c|c|c|} \cline { 2 - 4 } \multicolumn{1}{c|}{} & Daisy & Rose & Total \\ \hline Red & 0.3 & 0.4 & 0.7 \\ \hline Yellow & 0.5 & 0.4 & 0.9 \\ \hline White & 0.2 & 0.3 & 0.5 \\ \hline Total & 1.0 & 1.0 & 1.0 \\ \hline \end{tabular} \][/tex]

Now let’s explore the options for indicating an association between the categorical variables.

1. The value of [tex]$G$[/tex] is similar to the value of [tex]$H$[/tex].
- [tex]\( G = 0.2 \)[/tex]
- [tex]\( H = 0.3 \)[/tex]
- The difference [tex]\( |G - H| = |0.2 - 0.3| = 0.1 \)[/tex]

2. The value of [tex]$B$[/tex] is similar to the value of [tex]$E$[/tex].
- [tex]\( B = 0.4 \)[/tex]
- [tex]\( E = 0.4 \)[/tex]
- The difference [tex]\( |B - E| = |0.4 - 0.4| = 0 \)[/tex]

3. The value of [tex]$G$[/tex] is not similar to the value of [tex]$H$[/tex].
- This suggests a large difference, but as calculated above, [tex]\( |G - H| = 0.1 \)[/tex], which is a small difference.

4. The value of [tex]$B$[/tex] is not similar to the value of [tex]$E$[/tex].
- This suggests a large difference, but as calculated above, [tex]\( |B - E| = 0 \)[/tex], which is identical.

Given these comparisons, the most likely indicator of an association between the categorical variables is if the values are similar. The closest values in our table are [tex]$B$[/tex] and [tex]$E$[/tex] with [tex]\( |B - E| = 0 \)[/tex], which is exactly the same.

Therefore, the correct answer is:
The value of [tex]\( B \)[/tex] is similar to the value of [tex]\( E \)[/tex].
