At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and 12 chose science. He used this data to draw the inference that about 25% of middle school students will indicate science is their favorite subject. If there are 200 students altogether, did he make a reasonable inference?

The correct answer is 24% because when u use the data and you cross multiply to get 2400/50=50x/50 then u get 48. Then say 48/200times a 100 which gives u the 24% of the students who love science in the whole school
