(a) Use the following data to compute a 95% CI for ₁1 - H₂: m = 661, x = 2228, s₁ = 1518, n = 405, y = 2634, and (Round your answers to two decimal places.) Does the resulting interval suggest that μ₁ −μ₂ has been precisely estimated? O The interval is fairly narrow, which suggests a precise estimate. O The interval is fairly wide, which does not suggest a precise estimate. O The interval is fairly narrow, which does not suggest a precise estimate. The interval is fairly wide, which suggests a precise estimate. $₂ You may need to use the appropriate table in the Appendix of Tables to answer this question. = 1138. (b) Use the following data to compute a 95% upper confidence bound for μ₁ −μ₂: m = 50, x= 43,600, s₁= 2500, n = 50, = 36,600, and s₂ = 1800. (Round your answer to two decimal places.)
