Question

lorie wants to determine the average amount of time that students at her school spend on the computer each day. there are 350 students in 15 classes. the number of boys and girls is approximately equal. which is the most random sample? 50 students in the art club 40 girls on her soccer team 2 students from each of the 15 classes 10 students from each of the 3 computer electives

Explanation:

A random sample should be representative of the entire student - body. The art club, soccer team, and computer electives are specific subsets with possible biases. Selecting 2 students from each of the 15 classes spreads the sample across all classes and is more likely to be representative of all students in terms of gender, interests, etc.

Answer:

C. 2 students from each of the 15 classes
