What is the value of F6 if they use a 3-day weighted moving average with W1 = 0.6, W2 = 0.2, and W3 = 0.2?


A) 51.4 B) 53.4 C) 58.6 D) None of the above

Respuesta :

The value of F6, if they use a 3- day weighted moving average is 53.4.

Explanation:

From the given data,  the weighted moving average is

W1 = 0.6

W2 = 0.2

W3 = 0.2

To find the value of F6, the 3-day weighted moving average is used

The formula used to calculate is, where W is the weighted moving average and D is the days sold.

 =  W1 D1 + W2 D2 + W3 D3

 = 0.6 (53) + 0.2(50) + 0.2(48)

 = 53.4

Thus the value of F6 is 53.4.
