Answer:
C.
Step-by-step explanation:
On a two-way frequency table, marginal frequency can be obtained by adding the values of each of the two individual rows separately and obtain the total for each; and adding the values of each of the two individual columns separately rows and obtain the total for each. In the end, the column addition of the total of each of the separate two rows and row addition of the separate two columns must be equal at the lower bottom right corner.
Based on the above, option C. is the two-way frequency table that correctly shows the marginal frequencies.
