Basic Question 0 of 5
The following model was fitted to a sample of supermarkets to explain profit levels:
Y-hatt = profits in thousands of dollars
X1t = food sales in tens of thousands of dollars.
X2t = nonfood sales in tens of thousands of dollar.
Y-hatt = 132.3 + 0.031 X1t + 0.089 X2t + et
where
Y-hatt = profits in thousands of dollars
X1t = food sales in tens of thousands of dollars.
X2t = nonfood sales in tens of thousands of dollar.
For a $30,000 increase in food sales, by how much would the predicted value of the dependent variable change?

danlan2 | in sales in tens of thousands, $30000 is converted to 3 in X_{1t} |
cfastudypl | thanks danlan2. 0.031*3 = 0.093. |

I passed! I did not get a chance to tell you before the exam - but your site was excellent. I will definitely take it next year for Level II.
