SCENARIO 14-20-B
You Are the CEO of a Dairy Company $\left( X _ { 1 } \right)$

SCENARIO 14-20-B
You are the CEO of a dairy company. You are planning to expand milk production by purchasing
additional cows, lands and hiring more workers. From the existing 50 farms owned by the company,
you have collected data on total milk production (in liters) , the number of milking cows, land size (in
acres) and the number of laborers. The data are shown below and also available in the Excel file
Scenario14-20-DataB.XLSX.
MILK 84686 101876 103248 70508 76072 86615 87508 105195 120351 68658
You believe that the number of milking cows $\left( X _ { 1 } \right)$ , land size $\left( X _ { 2 } \right)$ and the number of laborers $\left( X _ { 3 } \right)$ are the best predictors for total milk production on any given farm.
-Referring to Scenario 14-20-B, which of the following is a correct interpretation for the slope coefficient of the number of laborers?

A) On average, the addition of one laborer is estimated to increase total milk production by 6848.1868 liters while holding constant the effects of the land size and the number of
Milking cows.
B) On average, the addition of one laborer is estimated to increase total milk production by 6848.1868 liters regardless of the effects of the land size and the number of milking
Cows.
C) On average, one additional liter of total milk production is estimated to increase the number of laborers by 6848.1868 while holding constant the effects of the land size and
The number of laborers.
D) On average, one additional liter of total milk production is estimated to increase the number of laborers by 6848.1868 liters regardless of the effects of the land size and the
Number of milking cows
