Both columns add up fill by subtraction

Consider the following ANOVA table for a randomized block design — Treatments: sum of squares 48, degrees of freedom 4, mean squares 12, F calculated β\beta; Blocks: sum of squares 72, degrees of freedom 3, mean squares 24, F calculated 12; Error: sum of squares α\alpha, degrees of freedom m, mean squares γ\gamma; Total: sum of squares 144, degrees of freedom 19. Which of the following statements are true?

  1. A.α=20\alpha = 20
  2. B.β=6\beta = 6✓ Correct
  3. C.m = 10
  4. D.γ=2\gamma = 2✓ Correct

You have the answer. Trap Analysis is why the other three were written.

Not a worked solution repeated four times — the specific reasoning error each wrong option was built to reward, and why this one tests execution slip.
