Question

Angie takes a random sample of 100 students in her school and finds that 58% of the sample prefers art over music. There are 1,200 students in the school. Based on the sample proportion, how many students in the school would be expected to prefer art over music?

Answer 1

696 students

Explanation:

First we can see that 1200 is 12 times 100. We can confirm this by doing 1200/100 =12. Then we see that 58 students out of each 100 like art over music. So we can do 58*12= 696 because we are just multiplying the ratio of 1:12 to 58:696
