A randomized block design is used to test the null hypothesis that mean responses are identical under five treatments. Using four levels for the blocking factor, the following data are obtained: SSTR = 84; SSBL = 132; TSS = 288. Calculate the mean square for blocking (MSBL). Hint: First, complete the ANOVA table.
