Frаme scоre in beef cаttle is bаsed оn height at the hips and is used as a measure оf skeletal size. Frame scores range from 1 to 10 with a higher number indicating a taller animal. Independent random samples of frame scores were selected from the Angus and Simmental breeds of beef cattle with the following results: Angus Simmental 5 7 6 7 7 8 5 6 7 7 6 We use Analysis of Variance to test the null hypothesis that the breed means for frame score are equal (use α = 0.05). Which one of the following is not an assumption that must be met in order for the Analysis of Variance procedures used in this problem to be valid?
