Question

In a survey at a local university, 60% of students say that they get less than the recommended eight hours of sleep per night. In a group of 4600 students, how many would you expect to get eight hours or more hours of sleep per night

Answer 1

Given:

In a survey at a local university, 60% of students say that they get less than the recommended eight hours of sleep per night.

The number of students = 4600

So, the number of students who get less than the recommended eight hours of sleep per night =

$60\%*4600=\frac{60}{100}*4600=2760$

We will find the number of the students who get eight hours or more hours of sleep per night = 4600 - 2760 = 1840

So, the answer will be 1840 student
