Here is data resulted from an experiment to investigate whether yield from a certain chemical process depended either on the formulation of a particular input or on mixer speed. A statistical computer package gives (SS is sum of squared deviation): SS(Form) = 2253.44, SS(Speed) = 230.81, SS(Form*Speed) = 18.58, and SSE = 71.87 a) Does there appear to be interaction between the factors? (using a significance level of 0.05) b) Does yield appear to depend on either formulation or speed? (using a significance level of 0.05) c) Calculate estimates of the main effects. d) Write the formula for calculation of the residuals. Do not calculate the reseals.
