where Y represents hourly worker compensation (in dollars) and X represents hourly production of microchips (e.g., 50.5=50.5 chips): 1. State your hypothesis. 2. What are your cases/unit of analysis? 3. Calculate the regression equation (intercept and slope) and R2 4. Interpret the equation results (intercept, slope, r and R) with respect to the hypothesis. 4. Lastly, what are the implications of reversing the causal direction (try it and see: make x into y and y into x)?
