#### Answer

Variance:$979338.44 \$^2.$
Standard deviation:$989.62\$$
Range:3335\$.

#### Work Step by Step

By using the results from before: $\mu=51596.6\$.$
Variance=$\frac{\sum (x-\mu)^2}{n}=\frac{(54410-51596.6)^2+(51991-51596.6)^2+...+(50875-51596.6)^2}{10}=979338.44 \$^2.$
Standard deviation=$\sqrt{variance}=\sqrt{979338.44 \$^2}=989.62\$$
Range=maximum value-minimum value=54410\$-50875\$=3335\$.
