[tex]\text{Answer : }\sqrt[]{2.496}\text{ or 1.58}[/tex]

[tex]\begin{gathered} \text{Simplify : }\sigma\text{ = }\sqrt[]{\frac{(1.5)^2+(-2.1)^2+(-0.5)^2+(1.4)^2+(1.9)^2}{5}} \\ \sigma\text{ = }\sqrt[]{\frac{2.25\text{ + 4.41 + 0.25 + 1.9}6\text{ + 3.61}}{5}} \\ \sigma\text{ = }\sqrt[]{\frac{12.48}{5}} \\ \sigma=\text{ }\sqrt[]{2.496} \\ \sigma\text{ = 1.58} \end{gathered}[/tex]
