Step-by-step 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
