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 all together, did he make a reasonable inference?
A No, Mr. Yule's sample is biased and too small to be representative of the population
B Yes, Mr. Yule's sample is small and biased, so it is representative of the population
C No, Mr. Yule's percentage is too large. He should have used 6%.
D Yes, Mr. Yule's sample is random and representative of the population
