You wish to estimate the model Weighti = β1 + β2Heighti + µi, and everyone in your sample weighs exactly 70kg, although the heights range from 1.6m to 1.9m. Derive the OLS estimates βˆ1 and βˆ2 (note that I am asking for the actual number values of βˆ1 and βˆ2. This can be done, even though I haven't given you the complete dataset. There are multiple ways to do this). What would the RSS be equal to? Why?
