Consider the following incomplete ANOVA table:

Source SS DF MS F A 50.00 1 50.00 ?

B 80.00 2 40.00 ?

AB 30.00 2 15.00 ?

Blocks 10.00 1 ?

Error ? ? ?

Total 185.00 11

(a) The pure error estimate of the standard deviation of the sample observations is 1.73.

True False

(b) Suppose that the experiment had not been run in blocks; that is, it is now a CRD. The number of degrees of freedom for error would now be __________________.

(c) The error mean square in the CRD would be ___________________.

(d) The F-test statistic for interaction in the CRD is significant at ???? = 0.05.

True False
