Question

In a survey at a local university, 28% of students say that they get less than the recommended eight hours of sleep per night. In a group of 3500 students, how many would you expect get eight or more hours of sleep per night?

Answer 1

If 28% get less than 8 hours, what percent gets 8 or more hours? 1-.28 = .72 = 72%

 

Multiply that percentage by the number of students to get your answer
