Can you please solve all parts of the question manually. Thank you! 2. Following are data on the worldwide shipments of personal computers (in thousands)according to Dataquest.(a) Fit a linear model (T = bo + bịt) to this data using linear regression. Write theequation for the model, calculate the fitted values and the residuals. Calculate MSEand MAD for this model.%3D(b) Repeat the procedures in (a), but for the quadratic model (T† = bo + bịt+ bzt²), usingthe quadratic regression option in your calculator.(c) Compare MSE for both models and MAD for both models to decide which model fitsbetter. Do not look at R? calculations or other traditional regression diagnostictools (they are not appropriate for time series - the observations are not independent).Year1985Shipments (1000)14, 70515,06416,67618,06121,32723,73826,96632,41138,85147,89460,17171,06582,40097,3211986198719881989199019911992199319941995199619971998
