Question

Mr. Rodriguez asked 60 randomly chosen students from each grade level at Willowbrook School about their favorite types of reading materials. Of those 60 students, 12 chose science fiction. Mr. Rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction. If 150 students attend the school, did he make a reasonable inference? Explain.

Answer 1

Yes, Mr. Rodriguez did make a reasonable inference because his sampling he did was random, nonbiased, and reasonably large compared to the school population. and 12 is 20% of 60.
