# Quantitative Methods (5 Stats Problem)

I need help with the included statistics problems. These are practice problems and I am unable to get a good grasp in this area.

11. Given the following data on the number of pints of ice cream sold at a local ice cream store for a 6-period time frame:

Period Demand

1 200

2 245

3 190

4 270

5 280

6 300

Compute a 3-period moving average for period 4.

12. The following data summarizes the historical demand for a product

Month Actual demand

March 20

April 25

May 40

June 35

July 30

August 45

Use a four period moving average and determine the forecasted demand for July and August.

13. The following data summarizes the historical demand for a product

Month Actual demand

March 20

April 25

May 40

June 35

July 30

August 45

Use exponential smoothing with and the smoothed forecast for July is 32 and determine August and September's smoothed forecasts.

14. The following sales data are available for 1998-2003 inclusive:

Year Sales

1998 7

1999 12

2000 14

2001 20

2002 16

2003 25

Determine a 4-year moving average forecast for each possible year.

15. Robert has the following accounts on money spent on gambling and winnings:

Money spent Money won

1000 2500

1200 4000

11800 4500

2000 4600

2500 5000

2800 4800

3500 5600

4000 6000

4200 5800

7000 X

Using linear regression, predict x.

#### Solution Summary

This solution calculates the period moving average, forecasted demand, exponential smoothing, and uses linear regression to compute the value of 'x'.
