(a) Use the following data to compute a 95% CI for μ₁ −μ₂: m = 664, X = 2218, s₁ = 1511, n = 411, = 2633, and $₂ = 1148. (Round your answers to two decimal places.) Does the resulting interval suggest that ₁ - ₂ has been precisely estimated? The interval is fairly narrow, which does not suggest a precise estimate. The interval is fairly narrow, which suggests a precise estimate. The interval is fairly wide, which does not suggest a precise estimate. The interval is fairly wide, which suggests a precise estimate. (b) Use the following data to compute a 95% upper confidence bound for μ₁ - H₂: m = 45, x = 42,100, $1 = 2400, n = 45, y = 36,100, and s₂ = 1500. (Round your answer to two decimal places.) у

(a) Use the following data to compute a 95% CI for μ₁ −μ₂: m = 664, × = 2218, s₁ - y 2633, and s₂ = 1148. (Round your answers to two decimal places.) Does the resulting interval suggest that μ₁-₂ has been precisely estimated? O The interval is fairly narrow, which does not suggest a precise estimate. The interval is fairly narrow, which suggests a precise estimate. The interval is fairly wide, which does not suggest a precise estimate.
