• Above equation referred to as simple linear regression. We would be interested in estimating β0 and β1 from the data we collect

443322110 xXxxY

Basic Assumptions..

• We want to see if there is a linear relationship, i.e.

• we want to see if the slope ( β ) is something other than zero.

• Our research hypothesis becomes: H1: ≠ O Thus the null hypothesis becomes: H0: = O
