Question

In a sample of 50 randomly selected students at a school, 38 students eat breakfast every morning. There are 652 students in the school. using these results, predict the number of students that eat breakfast.
A. 76
B.123
C.247
D.496

Answer 1

For the sample:
$\frac{38}{50} = 0.76 = 76\%$

Applying this to the whole population:

$652 \times \frac {38}{50} = 495.52$

Since we can't have "0.52 of a person" we roudn to the neares whole, or 496.
