Question 103

Short Answer

Find a 95 percent confidence interval for μ1 − μ2, where n1 = 9, n2 = 6, Find a 95 percent confidence interval for μ<sub>1</sub> − μ<sub>2</sub>, where n<sub>1</sub> = 9, n<sub>2</sub> = 6, <sub>1</sub> = 64, <sub>2</sub> = 59, s<sub>1</sub><sup>2</sup> = 6, and s<sub>2</sub><sup>2</sup> = 3. (Assume equal population variances.) 1 = 64, Find a 95 percent confidence interval for μ<sub>1</sub> − μ<sub>2</sub>, where n<sub>1</sub> = 9, n<sub>2</sub> = 6, <sub>1</sub> = 64, <sub>2</sub> = 59, s<sub>1</sub><sup>2</sup> = 6, and s<sub>2</sub><sup>2</sup> = 3. (Assume equal population variances.) 2 = 59,
s12 = 6, and s22 = 3. (Assume equal population variances.)
