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

Maru [420]

Answer:

The Second Method

Step-by-step explanation:

APE (Absolute Percentage Error) = absolute difference / actual * 100

APE for First method = 61.93

APE for second method = 54.97

MAPE (Mean absolute Percentage error) = Sum of absolute Percentage error/ Number of observations. ( i.e., 4)

Then,

MAPE for the first method = 61.93 / 4 = 15.482

MAPE for the second method = 54.97 / 4 = 13.472

So, MAPE for second method is less than the MAPE for first method.
