We would be interested in estimating β0 and β1 from the data we collect
7. 7. 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
