Suppose the Kalamazoo Brewing Company (KBC) currently sells its microbrews in a seven-state area: Illinoise, Indiana, Michigan, Minnesota, Mississippi, Ohio, and Wisconsin. The company's marketing department has collected data from its distributers in each state. This data consists of the quantity and price (per case) of microbrews sold in each state, as well as the average income (in thousands of dollars) of consumers living in various regions of each state. The data for each state are available via the link below--please note there are multiple tabs at the bottom of the spreadsheet, each refers to one of the seven states selling the Kalamazoo Brewing Company’s microbrews.

Answer:

The least squares estimates of Ohio’s demand for KBC microbrews is Quantity = 1.57Price + 14.00Income.

Explanation:

Note: See Sheet1 of the attached excel for the replication of the data given in the question and Sheet2 for the regression analysis output.

In the third table in the Sheet2, the second column is for the coefficients where, by rounding to 2 decimal places, we have:

Price = 1.57

Income = 14.00

Note: The intercept is 0 because a zero intercept was chosen in the analysi.

Based on the above, the least squares estimates of Ohio’s demand for KBC microbrews can be written as follows:

Quantity = 1.57Price + 14.00Income

To run the regression from Sheet1 in order to obtain the output in Sheet, follow his process:

Click the “Data” menu, and then the “Data Analysis” tab. From the new window, scroll down to find and click on "Regression" and then click “OK”.

In the new window, click in the box of “Input Y Range”, and then select the column containing the Quantity data as the dependent variable. Also in the new window, click in the box of “Input X Range”, and then select the column containing the both Price and Income data as the independent variables. Also, select "Labels", "Confidence level (95%)", and "Constant is Zero". Then click "OK" to obtain the output in Sheet2.
