The manager of a swine operation wants to compare the litter sizes of three pigs of pigs – Duroc, Yorkshire, and Large White. The manager obtains a random sample of litter sizes of sows of the three breeds as shown in the table below. Use Analysis of Variance to test at the 0.05 significance level if there is a difference in the average litter sizes of the three breeds of pigs. Litter size Large White Duroc Yorkshire 10 6 11 6 7 8 8 9 13 12 4 10 6 6 10 10 12 5 6 8 6 Total 42 67 64 Average 8.4 6.7 10.7 What are the mean squares (MS) for breed and error in the Analysis of Variance table given that the sums of squares are 131.81, 59.18, and 72.63 for total, breed, and error, respectively.
