Suppose we have the following data that identifies the overall discount of all items purchased in a transaction (as a percentage), as well as the profit generated from that transaction.
Transaction ID | Overall Discount | Profit ($) |
1 | 4 | 90 |
2 | 4 | 80 |
3 | 5 | 80 |
4 | 5 | 75 |
5 | 6 | 70 |
6 | 6 | 60 |
Which of the models below represents the linear regression model
that predicts profit as a function of coupon percentage?
Profit = 125.83 – 10*(Overall Discount)
Profit = 10.82 – 0.077*(Overall Discount)
Profit = 16.97 – 0.18*(Overall Discount)
Profit = 94.33 – 5.29*(Overall Discount)
