Summarize two-category data with two-way tables and interpret joint, marginal, and conditional relative frequencies.
Compute a row conditional relative frequency
Problem
A table cell has count \(8\) in a row total of \(15\). Find the row conditional relative frequency.
Big Picture
What this problem is really about
Conditioning changes the reference group, and the denominator must follow that change. When the condition names a row, restrict attention to that row, place its total in the denominator, and compare the requested cell count with only those observations.
