Add up the number of students within the random sample data:
32+26+28+22 = 108

We can then use proportional fractions / cross-multiply to answer the question.

In a sample size of 108 students, 32 of them preferred Movie A.
There are 900 students in total.


(32)/(108) =(x)/(900)

32*900 = 28800

108*x = 108x

108x = 28800

x =
266(2)/(3) or
(800)/(3)

In decimal form that is approximately 266.667 and round that to the nearest whole number, you get 267 students who would prefer Movie A.
