Extracted text: Two samples are taken with the following sample means, sizes, and standard deviations T1 = 22 ã2 = 20 n1 = 71 n2 = 69 81 = 5 s2 = 2 Estimate the difference in population means using a 95% confidence level. Use a calculator, and do NOT pool the sample variances. Round answers to the nearest hundredth. < 41="" -="" 42="">
