Answer

Explanation:

Step1: Calculate number of boys with A

Total A's are 28 and 16 girls received A's. So number of boys with A is $28 - 16=12$.

Step2: Calculate number of boys with B

Total B's are 54 and 30 girls received B's. So number of boys with B is $54 - 30 = 24$.

Step3: Check total number of boys

We know there are 48 boys who received A, B or C. And number of boys with A is 12, with B is 24 and with C is 12 ($12 + 24+12=48$).

Step4: Calculate number of girls with C

Total C's are 24 and 12 boys received C's. So number of girls with C is $24 - 12 = 12$.

Step5: Calculate total number of girls

Total sophomores are 106 and 48 are boys. So number of girls is $106 - 48=58$. And $16 + 30+12 = 58$ (number of girls with A, B and C respectively).

Step6: Check total columns

Total A's: $12 + 16=28$. Total B's: $24 + 30 = 54$. Total C's: $12+12 = 24$. Total students: $48 + 58=106$.

Answer:

The second two - way table (Boys: 12, 24, 12, 48; Girls: 16, 30, 12, 58; Total: 28, 54, 24, 106) represents the information.
