# Manufacturing company

A random sample of 8 manufacturing companies is selected from a population of manufacturing companies. The market values (in millions of rands) of these 8 manufacturing companies are:

17 65 117 206 172 181 221 94

What is the lowest and highest market value?
Find the mean.
Draw the box and whisker plot (show all calculations)
Calculate the median.

a =  17
b =  221
m =  134.125
m2 =  144.5

### Step-by-step explanation:

$b=221=221$
$m=\frac{17+65+94+117+172+181+206+221}{8}=\frac{1073}{8}=134\frac{1}{8}=134.125$
${m}_{2}=\frac{117+172}{2}=\frac{289}{2}=144\frac{1}{2}=144.5$
