When Testing H0: μ1 − μ2 = 2, HA: μ1

question 68

Short Answer

When testing H0: μ1 − μ2 = 2, HA: μ1 − μ2 > 2, where When testing H<sub>0</sub>: μ<sub>1</sub> − μ<sub>2</sub> = 2, H<sub>A</sub>: μ<sub>1</sub> − μ<sub>2</sub> > 2, where <sub>1</sub> = 522, <sub>2</sub> = 516, σ<sub>1</sub><sup>2</sup> = 28, σ<sub>2</sub><sup>2</sup> = 24, n<sub>1</sub> = 40, n<sub>2</sub> = 30, at α = .01, what is the test statistic? (Assume unequal variances.) 1 = 522, When testing H<sub>0</sub>: μ<sub>1</sub> − μ<sub>2</sub> = 2, H<sub>A</sub>: μ<sub>1</sub> − μ<sub>2</sub> > 2, where <sub>1</sub> = 522, <sub>2</sub> = 516, σ<sub>1</sub><sup>2</sup> = 28, σ<sub>2</sub><sup>2</sup> = 24, n<sub>1</sub> = 40, n<sub>2</sub> = 30, at α = .01, what is the test statistic? (Assume unequal variances.) 2 = 516, σ12 = 28,
σ22 = 24, n1 = 40, n2 = 30, at α = .01, what is the test statistic? (Assume unequal variances.)
