Step-by-step explanation:
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:
<h2>How many car accidents involve airbag malfunctions?</h2><h2 />
This is because there's no need to survey an entire population for accurate results.
The other 3, regarding Colorado residents, middle school students, and classmates are considered a population.
For testing the amount of car accidents, a population is not needed.

On the graph we have points x:y of
3:5
6:10
12:20
which are all in the ratio 3:5, a slope of 5/3.
3:5=9:y
y=9×5/3 = 15
Answer: C (9,15)
