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:
Step-by-step explanation:
12/60 students chose science fiction
Let x/ 150 students attend the school
60x = 12× 150
60 x = 1800
X = 1800 ÷ 60
X =30
It shows the students have very low interest in science fiction.
