• If we only have ONE independent variable, the model is
• 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
