Which of the following correctly describes the F statistic for the completely randomized design?
A) It equals the ratio of mean squares for treatments (MST) to mean squares for error (MSE).
B) It equals the ratio of sum of squares for treatments (SST) to sum squares for error (SSE).
C) It equals the ratio of sum of squares for error (SST) to total sum of squares (Total SS).
D) All of these.
E) None of these.

The F statistic for the completely randomized design equals the ratio of mean squares for treatments (MST) to mean squares for error (MSE). Therefore, option A is the correct choice. Option B is incorrect because it refers to the sum of squares instead of the mean squares. Option C is also incorrect because it refers to the sum of squares for error and total sum of squares instead of the mean squares. Option D is incorrect because only option A is correct. Option E is also incorrect because at least one of the options is correct.
