Question

In a survey at a local university 32% of students say they get less than the recommended eight hours of sleep per night. In a group of 3330 students how many would you expect to get 8 or more hours?

Answer 1

2264 students get 8 or more hours of sleep.

Explanation:

We are given that 32% of students say they get less than the recommended eight hours of sleep per night.

We are to find the number of students who get 8 or more hours of sleep.

Percentage of students who get 8+ hours of sleep = 100 - 32 = 68%

Number of students who get 8 or more hours = 68/100 - 3330 = 2264

Answer 2

2264 students

Explanation:

3330/100=33.3

100-32=68

33.3 x 68=2264.4
