Question

a conditional relative frequency table is generated by column from a set of data. the conditional relative frequencies of the two categorical variables are then compared. if the relative frequencies being compared are 0.21 and 0.79, which conclusion is most likely supported by the data? an association cannot be determined between the categorical variables because the relative frequencies are not similar in value. there is likely an association between the categorical variables because the relative frequencies are not similar in value. an association cannot be determined between the categorical variables because the sum of the relative frequencies is 1.0. there is likely an association between the categorical variables because the sum of the relative frequencies is 1.0.

Explanation:

Step1: Recall association concept

If relative - frequencies are very different, there is likely an association.

Step2: Analyze given frequencies

The relative frequencies 0.21 and 0.79 are quite different.

Answer:

There is likely an association between the categorical variables because the relative frequencies are not similar in value.
