Answer
Variance:$9493.16(million \$)^2.$
Standard deviation:$97.43 \ million \$$
Range:265m\$.
Work Step by Step
By using the results from before: $\mu=159.8 \ million.$
Variance=$\frac{\sum (x-\mu)^2}{n}=\frac{(332m-159.8m)^2+(302m-159.8m)^2+...+(67m-159.8m)^2}{10}=9493.16(million \$)^2.$
Standard deviation=$\sqrt{variance}=\sqrt{9493.16(million \$)^2}=97.43 \ million \$$
Range=maximum value-minimum value=332m\$-67m\$=265m\$.
