A sales manager for an advertising agency believes that there is a relationship between the number of contacts that a salesperson makes and the amount of sales dollars earned.
A regression analysis shows the following results:

Intercept -12.201 6.560 -1.860 0.100
Number of Contacts 2.195 0.176 12.505 0.000
What is the regression equation?
Select one:
