MAxx Inc. during the past six weeks indicate the number of jobs requests:

WEEK	1	2	3	4	5	6
Requests (Actual)	46	40	38	42	44	45

Required: Predict the number of requests for Week 7 using each of the following methods:

a.. A four-period moving average.

b. Exponential smoothing with a = .40. Forecast for Week 1 was 50.

2. Two independent methods of forecasting based on judgment and experience have been prepared each month for the past 11 months

Compute MAD and MSE for each forecast.

The forecasts and actual sales are as follows:

Month	SALES (ACTUAL)	FORECAST I	FORECAST II
1	780	770	778
2	789	785	788
3	794	790	792
4	780	784	798
5	778	770	774
6	772	768	770
7	765	761	759
8	775	771	775
9	786	784	788
10	790	788	788

11 795 800 795

3. An electronics company is looking to develop a regression model to predict the number of units sold for a special running watch. Data is provided below:

Sales (units)	Price ($)	Advertising ($)
500	100	50
480	120	40
485	110	45
510	103	55
490	108	40
488	109	30
496	106	45

a. Should this company use both price and promotion dollars, or just one of them only, to determine the sales? Perform data analysis and Explain. b. Use the model you determined (multiple regression) to predict sales if price is set at $125 and advertising is $55.
