A Rаndоmized Blоck Design is used tо compаre fleece weights of three breeds of sheep - Merino, Suffolk, аnd Dorset (we can think of the three breeds as being the three treatments).  The sheep are divided into two weight classes (i.e., two blocks).  Block one contains sheep weighing less than 150 lb and block two contains sheep weighing more than 150 lb.  The fleece weights (in pounds) are as follows:                    Merino          Suffolk          Dorset Block 1          13                  8                  9 Block 2          14                  9                 11                                                                          The partially completed ANOVA table for this experiment is as follows: Source     df          SS            MS            F      Total                29.33333 Breed              26.33333     13.16667    79.00003 Block                     Error                 0.33333        0.16667              We want to test the null hypothesis that the three breed means are equal vs. the alternative hypothesis that at least two of the breed means are different.  Using a signficance level of 0.05, which one of the following statements is the correct conclusion?
