Using proportions:
The proportion of students surveyed who saw the movie is:
12/40 = 0.3
We can use this proportion to predict how many students out of the whole school population of 500 saw the movie:
0.3 x 500 = 150
Therefore, it is predicted that 150 students at the school saw the new action movie over the weekend.
A teacher ask 40 randomly selected students if they watched the new action movie over the weekend. If 12 of the students surveyed saw the movie, predict how many of the 500 students at the school saw the movie?
