Question

Sicilia randomly selected 25% percent of the Sound Sleep email subscribers and asked them how many hours of sleep they average each night. Of the subscribers surveyed, 16 average less than 6 hours of sleep each night.
Based on the data, what is the most reasonable estimate of the number of Sound Sleep email subscribers who average less than 6 hours of sleep?

Answer 1

The answer would be 64, because 25% is a quarter of 100. That means you would have to multiply 16 by 4.
