(a) Does there appear to be interaction between the factors? Yes, there appears to be nteraction between the two factors. O No, there appears to be no interaction between the two factors. (b) Does yield appear to depend on either formulation or speed? Only formulation appears to have a highly statistically significant effect on yield. Only speed appears to have a highly statistically significant effect on yield. O Both formulation and speed appear to have a highly statistically significant effect on yield. Neither have a statistically significant effect on yield. ✓ (c) Calculate estimates of the main effects. (Let Factor A= formulation and Factor B= speed.) a₁ = â₂ = Â₁ = B₂ =
