andomized block design yielded the following Analysis of Variance table:
Source df SS MS F
Total 14 836
Treatments 4 501 125.25
Blocks 2 225 112.50
Error 8 110 13.75
Find the critical F value from the F tables that should be used to compare to the calculated F value for treatments. Assume that we will use a significance level (α) of 0.05.
