Question

Cinemaniac Movie Channel randomly selected 30% of its viewers and asked them how many movies they watch per month. Of the viewers surveyed, 27 watch more than 10 movies per month. Based on the data, what is the most reasonable estimate of the number of viewers who watch more than 10 movies per month?

Answer 1

90, because extrapolating 30% of viewers to 100% would be a 10/3 increase. A 10/3 increase of 27 would be 10*27/3 or 10*9 or 90.
