Two samples are taken with the following sample means, sizes, and standard deviations: \( \bar{x}_1 = 37 \) and \( \bar{x}_2 = 40 \) \( n_1 = 50 \) and \( n_2 = 73 \) \( s_1 = 5 \) and \( s_2 = 4 \) Estimate the difference in population means using a 91% confidence level. Use a calculator, and do NOT pool the sample variances. Round answers to the nearest hundredth. \[ < \mu_1 - \mu_2 < \]
