Summarize two-category data with two-way tables and interpret joint, marginal, and conditional relative frequencies.

Find row totals, column totals, and grand total

Problem

A two-way table has these \(\text{four}~\text{cell}~\text{counts}\): \(\text{freshmen}~\text{no}~\text{sports}~=~8\), \(\text{freshmen}~\text{sports}~=~12\), \(\text{sophomores}~\text{no}~\text{sports}~=~5\), \(\text{sophomores}~\text{sports}~=~15\). Find the row totals, column totals, and grand total.
