안녕하세요

Practice4 35번 문제에 대해서 질문 드립니다.

정답은 C라고 하셨는데 제 생각에는 지금 각 표본의 숫자를 확인할수 없어서 정확한 GPA를 알수는 없지만 3학년수가 4학년수보다 같은 다르든 어쨌던 화학 전공자의 GPA는 항상 물리전공자보다 높게 나오지 않나요?

안녕하세요 이연욱 샘입니다.

 

The number of Juniors majoring in Physics is not same as the number of Juniors majoring in Chemistry.

In addition, the number of seniors majoring in Physics is not same as the number of seniors majoring in Chemistry.

No one knows the number of juniors and seniors majoring in physics and chemistry.

 

Therefore, physics majors might have a higher GPA than chemistry major when juniors and seniors are grouped together.
