A randomized block design has 7 blocking levels and 5 treatment levels.Given the level of data, a nonparametric alternative to a randomized block design must be used to analyze the data.For the test of the null hypothesis that the treatment populations are equal at a 1% level of significance, the critical value of the test statistic is ___.
A)16.81
B)15.09
C)13.28
