We can calculate the predicted values for the monthly sales using the given linear regression equation:
Y = 2.6185 + 0.4369X
Where Y is the monthly sales and X is the number of customers (in hundred).
Using this equation, we get the following predicted values:
| Predicted Y: | 3.7986 | _____ __________ _________ ________ _________ __________ ______ __________ __________.
