Answer: Variance= 3933.806

Explanation: Variance measures the spread of the data. It shows how far the data is spread from its mean. It is calculated as,

[tex]variance= ∑\frac{x-mean}{n}[/tex]

Mean = 364.8333

[tex]variance = \frac{(422 - 364.333)^{2} + (332 - 364.333)^{2}+ (453 - 364.333)^{2} + (353 - 364.333)^{2} + (260 - 364.333)^{2} + (366 - 364.333)^{2} }{6}[/tex]

[tex]= \frac{23602.83}{6}

= 3933.806[/tex]

Therefore, the variance is $3933.806 dollars.
