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:

`(38)/(50) = 0.76 = 76\%`

Applying this to the whole population:


`652 * \frac {38}{50} = 495.52`

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