Consider the Below Set of Lengths for Questions $\begin{array}{l} 123 && 422 && 566 && 329 && 247 && 296 && 245 && 522\\ 362 && 593 && 229 && 475 && 357 && 227 && 489 && 326 \end{array}$

Short Answer

Consider the below set of lengths for questions:

$\begin{array}{l} 123 && 422 && 566 && 329 && 247 && 296 && 245 && 522\\ 362 && 593 && 229 && 475 && 357 && 227 && 489 && 326 \end{array}$
-Find the sample variance and standard deviation of the lengths.
