Exercise 6 Page 279

The last row and the last column show totals.

Like Basketball
Like Baseball Yes No Total
Yes 61 13 74
No 16 10 26
Total 77 23 100
Practice makes perfect
We know that 100 students were surveyed about whether they like baseball or basketball. To complete the two-way frequency table, we need to recognize that the last row and the last column show totals.
Like Basketball
Like Baseball Yes No Total
Yes 61 13 61+13
No 16 10 16+10
Total 61+16 13+10

Finally, note that the sum of the Total row and the Total column should add up to 100, the total number of students in the survey. This value should be written in the bottom right cell.

Like Basketball
Like Baseball Yes No Total
Yes 61 13 74
No 16 10 26
Total 77 23 100
