Darsh's simulated samples:

Sample 1 (size 50)

Sample 1 mean: 15.4

Sample 2 (size 50)

Sample 2 mean: 11.8

Sample 3 (size 100)

Sample 3 mean: 16.1

Sample 4 (size 100)

Sample 4 mean: 16.3

Darsh is trying to determine the average number of hours the students at his school study each week. He used a random number generator to simulate the possible results. His samples are shown.

If the school has 3,000 students, which sample size is more appropriate?
