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?

Yes, he made a reasonable inference by saying about 25 percent of students choose the science.

Step-by-step explanation:

Given that

Number of students for survey = 50

Number of students who choose science = 12

Now

Percentage of student who choose science =

Percentage of student who choose science =

Percentage of student who choose science = 24 %

Now as Mr. Yule said "about 25" percent of students choose the science it can be treated as reasonable approximation.

Now if the number of students in survey become 200, then we can expect 12 out of every 50 students would choose the science. So, in total 48 students would choose the science.

Now lets calculate the percentage of students who choose science.

Percentage of student who choose science =

Percentage of student who choose science =

Percentage of student who choose science = 24 %
