Answer:
(a) MAE = 5.20
(b) MSE = 10
(c) MAPE = 38.60%
(d) Forecast for week 7 = 14
Step-by-step explanation:
Note: See the attached excel for the calculations of the Error, Error^2, and Error %.
(a) mean absolute error
MAE = Total of absolute value of error / Number of observations considered = |Error| / 5 = 26 / 5 = 5.20
(b) mean squared error
MSE = Total of Error^2 / Number of observations considered = Error^2 / 5 = 150 / 5 = 10
(c) mean absolute percentage error (Round your answer to two decimal places.)
MAPE = Total of Error % / Number of observations considered = Error % / 5 = 193.02 / 5 = 38.60%
(d) What is the forecast for week 7?
Since the forecast is based on the naive method (most recent value), the forecast for week 7 is value for week 6. Therefore, we have:
Forecast for week 7 = 14
Answer:
S=98
Step-by-step explanation:
If S2 is 196 we can divide that by two and get our answer: s=98
To figure out the slope you would want to use this formula for 2 of the points: Y2-Y1/X2-X1.
if you followed this for (-3,-2) and (3,2), you would get 2-(-2)/3-(-3)
this would equal 4/6, which simplifies to 2/3
the slope of line p = 2/3x
30 since that’s the lowest number both 3 and 10 can fit in
