Use Minitab software to calculate all the 15 main and the interaction effects (1, 2, ..... ..1×2×3×4) 2. Extract the half fractional factorial design 2+¹ (Baby1) based on the confounding formula (4 = 123) and show it as a matrix 3. Use Minitab software to calculate all the main contrasts of the half fractional factorial design 2+1 (Baby1) 4. Write the Aliases Table and numerically prove the Confounding Pattern that connect effects (Parent) with contrasts (Baby 1) for the four main contrasts (₁→l₁). 123456ragMDSHS6 7 8 9 11 X₁ X₂ 1 -1 1
