Answer
Set A: mean = 11.8, range = 21
Set B: mean = 14.6, range = 5
Work Step by Step
To find the mean, we add up all of the values and divide by the total number of values.
Mean A: $\frac{0+12+7+19+21}{5} = 11.8$
Mean B: $\frac{13+16+15+17+12}{5} = 14.6$
To find the range, we subtract the smallest term from the largest term.
Range A: $21-0 = 21$
Range B: $17-12=5$
The mean of Set B is greater than the mean of Set A, but the range of Set A is greater than the range of Set B.
