Answer 1

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.

$\frac{32}{108} =\frac{x}{900}$

32*900 = 28800

108*x = 108x

108x = 28800

x = $266\frac{2}{3}$ or $\frac{800}{3}$

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.
