A twо-fаctоr fаctоriаl experiment is conducted to compare fleece weights of Merino, Suffolk, and Dorset ewes fed one of two diets. Two ewes of each breed are randomly assigned to each diet. The fleece weights (in pounds) are as follows: Merino Suffolk Dorset Diet 1 14 9 8 15 10 8 Diet 2 13 8 11 12 9 12 The partially completed ANOVA table is as follows: Source df SS MS F Total 66.2500 Diet 0.0833 0.0833 0.19992 Breed 46.5000 23.2500 55.79955 Diet x Breed 17.1667 Error 2.5000 0.41667 The correct degrees of freedom for total, diet, breed, diet x breed, and error, respectively, are:

The persоn in chаrge оf genetic evаluаtiоn of beef cattle wants to know if birth weights of calves are influenced by breed and if they are influenced by the region of the U.S. (i.e., Northern U.S. vs Southern U.S.) in which the calf is born. She has heard that calves born in the South are usually lighter at birth than are calves born in the North. In order to answer these questions, she sets up a 2 x 3 factorial experiment with 3 replications and obtains the birth weights (in pounds) shown in the following table: Angus Charolais Simmental North 85 93 91 85 92 92 83 94 92 South 85 84 82 76 85 83 74 83 83 The partially completed ANOVA table is as follows: Source df SS MS F Total 548.00 Location Breed 174.33 87.165 13.643 Location x breed 9.00 4.500 Error Calculate the mean square (MS) for location.
