Answer
Variance:$4.7664 \cdot10^{13} \ (\$)^2$.
Standard deviation:$6,903,911.93 \$$
Range:$19,628,584\$$.
Work Step by Step
By using the results from before: $\mu=12,898,007 \ \$.$
Variance=$\frac{\sum (x-\mu)^2}{n}=\frac{(17,668,241-12,898,007)^2+(1-12,898,007)^2+...+(14,765,410-12,898,007)^2}{5}=4.7664 \cdot10^{13} \ (\$)^2.$
Standard deviation=$\sqrt{variance}=\sqrt{4.7664 \cdot10^{13} \ (\$)^2}=6,903,911.93 \$$
Range=maximum value-minimum value=$19,628,585 \$-1 \$=19,628,584\$$.
