Regression equation, sum of squares for Error and Total sum of squares.
An experiment was performed on a certain metal to conclude if the strength is a function of heating time. Results based on 10 metal sheets are given below. Use the simple linear regression model.
SSxx = 14 SSyy = 18 SSxy = 14 ∑X = 30 and ∑Y = 40
Agree on SSE, SS (Total) and the explained sum of squared variation SSR and find the estimated y intercept slope and write down the regression equation.
