Answer

Explanation:

Step1: Calculate percentage for statement A

The number of students who do not use school - buses is 56, and the total number of students is 150. The percentage is $\frac{56}{150}\times100%\approx37.33%\approx37%$.

Step2: Calculate percentage for statement B

The number of grade - 12 students who use school buses is 33, and the total number of grade - 12 students is 50. The percentage is $\frac{33}{50}\times100% = 66%$.

Step3: Calculate percentage for statement C

The number of grade - 10 students who do not use school buses is 16, and the total number of grade - 10 students is 50. The percentage is $\frac{16}{50}\times100%=32%\neq11%$.

Step4: Calculate percentage for statement D

The number of grade - 10 students who use school buses is 34, and the total number of students who use school buses is 94. The percentage is $\frac{34}{94}\times100%\approx36.17%\neq34%$.

Step5: Calculate percentage for statement E

The number of grade - 11 students who do not use school buses is 23, and the total number of students is 150. The percentage is $\frac{23}{150}\times100%\approx15.33%\approx15%$.

Answer:

A. 37% of all students do not use school buses B. 66% of students in grade 12 use school buses E. 15% of all students are in grade 11 and do not use school buses
