2.) A whisking expert is interested in determining the best brand (KitchenAid, Hamilton Beach, Smeg) and configuration (handheld, stand) of electronic mixing tool to purchase. Therefore, a 3x2 factorial experiment is set up. Originally it was intended to have two replicates at each treatment level, but some particular mixers were defective and broke before they could be used. The values in following table presents the observed value of Yijk , which denotes the number of minutes it takes to whip meringue for the km replicate of the jth conguration and ith brand, among the remaining N = 8 observations. "B1 (handheld mixer) : B2 (stand mixer) A1 (KitchenAid) 15 - 1 13 12 A2 (Hamilton Beach) 17 16 14 - ' A3 (Smeg) ' - 15 12 ' - a. Below is the statistical model for this 3x2 factorial experiment. Please write the appropriate degrees of freedom for each term in the model above each term. I3 \"(L (L Y\": u+OLl+ Bf\"; b. Calculate the marginal mean of KitchenAid mixers
