If 30 people claimed that they get an average of seven hours of sleep, how many people claimed that they get at least eight hours of sleep each night? [type your answer as a number.]

Step-by-step explanation:

We know that 30 people claimed that they get an average of seven hours of sleep. Using the circular diagram, we find that these 30 people represent 25% of the total number of people.

According to the graph, people that get at least eight hours of sleep each night represent 65%, that is, 50% of the people sleep eight hours and 15% sleep nine or more.

Therefore, 78 people claimed that they get at least eight hours of sleep each night.
