Did not reject H₀. The oral exam scores are not higher than the written exam scores. Reject H₀ if T⁺ ≤ T_.05,11 = 14 11ead627_0a05_4f53_93a1_91258bff9814_TB7056_00 T⁺ = 3.5 + 1 + 10 = 14.5 14.5 > 14; we do not reject H₀. The oral exam scores are not significantly higher than the written exam scores.
