Can Swim Cannot Swim Totals
7th Graders 15 60
8th Graders 45
Totals 65 40 105
The table shows data for seventh and eighth graders who can and cannot swim. How would you construct the missing parts of the two-way table?

7th Graders
15 60
8th Graders
45
Totals 65 40 105
To construct the missing parts of the two-way table, we can calculate the totals for each row and column based on the given data.
For the 7th graders:
- Can Swim: 15
- Cannot Swim: 60
- Total: 15 + 60 = 75
For the 8th graders:
- Can Swim: 65 (total can swim - 7th graders who can swim)
- Cannot Swim: 45
- Total: 65 + 45 = 110
Therefore, the completed two-way table would look like this:
Can Swim Cannot Swim Totals
7th Graders 15 60 75
8th Graders 65 45 110
Totals 80 105 185
