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.
Accepted Solution
A:
Answer: Yes, he makes a reasonable inference.Step-by-step explanation:Since we have given that Number of students = 60Number of chosen science students = 12Percentage of students who chose science is given by[tex]\frac{12}{60}\times 100\\\\=\frac{1}{5}\times 100\\\\=20\%[/tex]Since Mr. Rodriguez used the data to draw the inference that about 20% of middle school students prefer to read science fiction.So, he makes a reasonable inference.
