A package delivery company experiences high variability in daily customer demand, which in turn results in high variability in t

Ilya [14]

Solution :

Let :

X = number of overtime hours

S = total weekly salary

S = $12 \times 40 + 18 \times X$

S = 480 + 18X

E(S) = $480 + 18 \times E(X)$

$E(S) = 480 + 18 \times 15$

= 750

Mean of S = 750

Var (S) = $18^2 \times Var(X)$

Var(S) = $18^2 \times 4^2$

= 5184

Variance of S = 5184

The standard deviation equals square root of 5184 = 72
