An Engineer wanted to know whether the strength of two different concrete mix designs differed significantly. He randomly selected 10 cylinders of each mixture with the following results: Mixture A: 3960, 4090, 3100, 3830, 3200, 3780, 4080, 2940, 4040,3700 Mixture B: 4070, 4890, 5020, 4330, 4640, 5220, 4190, 3730, 4120, 4520 Determine whether mixture B is stronger than mixture A at Alpha = 0.05 level of significance. State the conclusion.
