You are filling in the ANOVA table values for an experiment using a randomized complete block design.In the experiment, there are 3 treatment groups and 8 blocks.The treatment sum of squares is 7200.The error sum of squares value is 4200.The F value (Fstat) that will be used to test the "equal treatment means" null hypothesis is
A)12.00
B)6.00
C)14.667
D)4.222
E)400.333

The F value is calculated as the ratio of the mean square for treatments to the mean square for error. The mean square for treatments is the treatment sum of squares divided by its degrees of freedom (3-1=2), and the mean square for error is the error sum of squares divided by its degrees of freedom (3*8-3-1=20). Thus, F = (7200/2) / (4200/20) = 12.00.
