Question about one-way ANOVA?

a) Can one-way ANOVAS can be negative

b) If all sample means are equal, MST = 0

c) The F-statistic can never be greater than MST.

d) MSE can be negative.

e) Mean squared test (MST) and mean squared error (MSE) will equal whenever the design is balanced.

a) false.

b) true (sum of difference^2 = 0)

c) false, since MSE is a pooled-variance and we can get some numbers with a variance < 1

d) false (the squaring removes the possibility of a negative value).

e) ?

I cannot figure out e)
