marishachu [46]

Answer:

a. MSE = 64.8

b. Forecast for month 8 is 14.

Step-by-step explanation:

MSE = \frac{sum (error)^{2} }{n-1} \\

where error= value-forecast

Using the most recent value as the forecast for the next period, we have forecasts for the months as;

(1,-) , (2,25) , (3,13) , (4,21) , (5,13) , (6,20) , (7,22)

error = (-, -12, 8, -8, 7, 2, -8, -)

error^{2} = (-, 144, 64, 64, 49, 4, 64, -)

sum(error^{2} ) = 389

MSE = \frac{389}{7-1} = 64.833333

Therefore, MSE = 64.8 (1 decimal place).

The Forecast for month 8 is 14 since we are using the most recent value as the forecast for the next period.
