question 4
(05.05 mc)

Explanation:

Joint relative frequency represents the proportion of a specific subgroup (here, female students who prefer dancing) out of the total population. The value 0.31 is the ratio of female students who prefer dancing to the total number of respondents, fitting this definition. Joint frequency uses raw counts, marginal frequency is a row/column total count, and marginal relative frequency is a row/column total proportion, which do not match 0.31.

Answer:

Joint relative frequency
