Answer 1

To construct the missing parts of the two-way table, we need to find the total number of students in each grade level and the total number of students who can swim in each grade level.

For the 7th graders:
Total number of 7th graders = 15 + 60 = 75
Total number of 7th graders who can swim = 15

So, the number of 7th graders who cannot swim = Total 7th graders - 7th graders who can swim = 75 - 15 = 60

For the 8th graders:
Total number of 8th graders = 45
Total number of 8th graders who can swim = 45

So, the number of 8th graders who cannot swim = Total 8th graders - 8th graders who can swim = 45 - 45 = 0

Now we can construct the missing parts of the two-way table:

8th Graders%09%0945%090%0945
