Frаme scоre in beef cаttle is bаsed оn height at the hips and is used as a measure оf skeletal size. Frame scores range from 1 to 10 with a higher number indicating a taller animal. A randomized block design is used to compare the frame scores of Angus and Simmental calves where the blocks consist of calves of similar ages. Three blocks are used, where block 1 contains calves that are 320 to 340 days of age, block 2 contains calves that are 341 to 360 days of age, and block 3 contains calves that are 361 to 380 days of age. The frame scores are as follows: Angus Simmental Block totals Block 1 5 6 11 Block 2 6 7 13 Block 3 7 8 15 Breed totals 18 21 39 The partially completed ANOVA table for this experiment is as follows: Source df SS MS F Total 5.500 Breed 0.167 0.167 0.25 Block 4.000 2.000 Error 1.333 0.667 What are the degrees of freedom for total, breed, block,and error, respectively?
