不会做的统计学题目

When I was in school, my teacher asked me what I want to be in the future, I had no idea at the time, because I didn’t think about the question before, now I have my dream, I have figured out what I want to be in the future, I want to be a teacher. This is my future ideal career, being a teacher not only fulfills myself, I also can implant my knowledge to my students. When I look at my teachers, I adore them so much, they learn so much knowledge, they can help us learn better, whenever we have questions, they can answer us immediately. I want to be one of them when I grow up, so I must study hard now.
