1.	a group of 100candidates have their average height 163.8cm with coefficient of variation 3.2 what is the standard deviation of their height
Answer» $\red{\textbf{Answer :-5.24}}$ Step-by-step explanation: $\red{\textbf{Given :-}}$ $Mean \: of \: height \: of \: 100 \: candidates(x)=163.8$ $Coefficient \: of \: variation \: ( C.V)=3.2$ $\red{\textbf{To find :-}}$ $<klux>STANDARD</klux> \: deviation \: of \: thei r \: height.$ $\red{\textbf{So, }}$ $= \LARGE \frac{\<klux>SIGMA</klux>}{x} \small \times 100 = 3.2$ $= \LARGE \frac{\sigma}{163.8} \small \times 100 = 3.2$ $\sigma = \LARGE \frac{3.2 \times 163.8}{100}$ $\sigma = 5.24$ $thus \: the \: standard \: deviatio n \: of \: their$ $height \:is \: 5.24$ $\red{\textbf{More information :-}}$ The Standard Deviation is a MEASURE of how spread out numbers are. Its symbol is σ (the GREEK letter sigma).
