Compute the Standard Deviation of a Variable from Raw Data
-In a random sample, 10 employees at a local plant were asked to compute the distance they travel to work to the nearest tenth of a mile. The data is listed below. Compute the range, sample standard deviation and sample variance of the data.
$\begin{array} { l l l l l l l l l l } 1.1 & 5.2 & 3.6 & 5.0 & 4.8 & 1.8 & 2.2 & 5.2 & 1.5 & 0.8 \end{array}$
