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) he should add the three numbers and divide by 3 because that is how one finds an average. b) he should poll more students to eliminate the variability caused by a sample size that is too small. c) he should take the middle number as his average since he has three observations. d) he should just find the average of 0.5 and 4 since 0 does not change anything when adding.
