A student runs an experiment to study the effect that a teacher has based on the size of their class.She uses 3 different teachers on 6 different class sizes. A)Teacher SS: 3 df; Class size SS: 5 df; SSE: 10 df B)Teacher SS: 2 df; Class size SS: 5 df; SSE: 11 df C)Teacher SS: 2 df; Class size SS: 8 df; SSE: 11 df D)Teacher SS: 2 df; Class size SS: 5 df; SSE: 10 df E)Teacher SS: 3 df; Class size SS: 4 df; SSE: 12 df
