Determine the standard deviation for the data.


\begin{gathered} \sigma=\sqrt[]{\frac{(28.9-8)^2+(28.9-16)^2+(28.9-19)^2+(28.9-20)^2+(28.9-23)^2_{}+(28.9-31)^2_{}+(28.9-35)^2_{}+(28.9-39)^2_{}+(28.9-48)^2_{}+(28.9-50)^2_{}}{10}} \\ =\sqrt[]{(1768.9)/(10)} \\ =13.3 \end{gathered}

So standard deviation is 13.3.
