Question #N98

A survey of 100 randomly selected students found that 60 students prefer to study in a quiet environment and 40 students prefer to study in a noisy environment. If 300 students are surveyed, how many are likely to prefer to study in a quiet environment?
A. 60
B. 120
C. 180
D. 240

Correct Answer is: C

The ratio of students who prefer quiet to the total number of students is 60/100 = 3/5. If 300 students are surveyed, we can multiply this ratio by 300 to estimate the number of students who prefer quiet: (3/5) * 300 = 180.
