2, 3, 4, 5, 6, 0.2, 0.1, 0.2, 0.2, 0.3

5.12444 \dots

Solution steps

Compute the average,

\overset{x}{ˉ} : 2.1

Compute

i = 1 \sum n (x_{i} - \overset{x}{ˉ})^{2} : 46.12

Compute the number of terms in the data set:

n = 10

Compute

Va r (X) = i = 1 \sum n \frac{( x _{i} - x ˉ ) ^{2}}{n - 1} : 5.12444 \dots

5.12444 \dots
