The answer is " $10 \% ,\text{upper limit}=52,\ and \ \text{lower limit}=28$ "

Step-by-step explanation:

Given value:

$\mu =40\\\\\sigma=4$

In point a:

Calculating the value of the coefficient of variation:

$\to C.V= \frac{6}{\mu} \times 100 \%\\\\ \to C.V= \frac{4}{\mu} \times 100 \% \\\\ \to C.V = 10 \%$

In point B:

when 88.9 \% of the value are lies then :

$\to \mu \pm 36\\\\\to \mu -36 = 40-3\times 4 = 40 -12 =28\\\\\to \mu +36 = 40+3\times 4 = 40 +12 =52$

$\text{upper limit}=52\\\\\text{lower limit}=28$
