Question

A group of 54 randomly selected students from one school district participated in a survey. Out of the 54 students in the survey, 9 are enrolled in band camp. If there are a total of 1,200 students in the school district, which estimate is reasonable for the number of students in the whole school district who are enrolled in band camp?

9/54 = x/1200

Cross multiply and solve for x.

200
1/6 = x/1200
x = 1200/6 = 200 yes
