A two-factor factorial experiment is conducted to compare litter sizes of Yorkshire and Landrace sows derived either from a line unselected for litter size or from a line that has gone through 15 years of selection for increased litter size. Two sows of each breed are randomly selected from each line. Their litter sizes are as follows: Yorkshire Landrace Unselected line 8 9 9 10 Selected line 11 11 10 9 The partially completed ANOVA table is as follows: Source df SS MS F Total 7.875 Line 3.125 3.125 3.57 Breed Line x Breed Error 3.500 0.875 What is the correct conclusion regarding the hypothesis test for breed? Use a significance level of 0.05.
