Dylan wanted to find the average number of hours per day that the students in his class practiced their instruments. He chose three students by drawing their names from a hat. What should he do to ensure that he has an accurate average for the class?

A dot plot going from 0 to 4. There is 1 dot above 0, 1 dot above 0.5, and 1 dot above 4.

He should add the three numbers and divide by 3 because that is how one finds an average.

He should poll more students to eliminate the variability caused by a sample size that is too small.

He should take the middle number as his average since he has three observations.

He should just find the average of 0.5 and 4 since 0 does not change anything when adding.
