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:

Coefficients Standard Error t-Stat p-value

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:

a.Y^= 2.195 - 12.201X

b. Y^= -12.201 + 2.195X

c.Y^= 12.201 + 2.195X

d.Y^= 2.195 + 12.201X

I also wanted to know if the negative sign for Y intercept will be ignored or not in the regression equation. Thank you!
