Question

In a survey at a local​ university 35%, of students say that they get less than the recommended eight hours of sleep per night. In a group of 2000 ​students, how many would you expect get eight or more hours of sleep per​ night?

Answer 1

1,500 students

Explanation:

Since in the question it is mentioned that 35% of students get less than 8 hours of sleep

And, there is a group of 2,000 students

Now the number of students who get eight or more hours per night sleep is

Suppose the total percentage be 100

Now the students more than 8 hours is

= 100 - 35%

= 0.75

And, the total students is 2,000 students

So, the number of students who get eight or more hours is

= 2,000 students × 0.75

= 1,500 students

The same is to be considered
