1 answer

To evaluate the statements, let's analyze the data provided in the table:

Total number of students surveyed = 150

  1. Total students who do not use school buses = 56

    • Percentage of all students who do not use school buses = (56/150) * 100 = 37.33%, so statement A is approximately correct, but not exact due to rounding.

  2. Students in Grade 12 who use school buses = 33

    • Percentage of students in Grade 12 who use school buses = (33/50) * 100 = 66%, so statement B is correct.

  3. Students in Grade 10 that do not use school buses = 16

    • Percentage of students in Grade 10 who do not use school buses = (16/50) * 100 = 32%, so statement C is incorrect.

  4. Students who use school buses = 94

    • Students in Grade 10 who use school buses = 34
    • Percentage of students who use school buses that are in Grade 10 = (34/94) * 100 = 36.17%, so statement D is incorrect.

  5. Students in Grade 11 who do not use school buses = 23

    • Percentage of all students who are in Grade 11 and do not use school buses = (23/150) * 100 = 15.33%, so statement E is approximately correct but not exact due to rounding.

Based on the evaluation:

  • Statement A is approximately correct but not exact.
  • Statement B is correct.
  • Statement C is incorrect.
  • Statement D is incorrect.
  • Statement E is approximately correct but not exact.

Thus, the final answers (statements that can be inferred from the data) are:

B. 66% of students in grade 12 use school buses.
