The diameter of steel rods manufactured on two different extrusion machines is being investigated. Two random samples of sizes n1 - 15 and n2 - 17 are selected, and the sample means and sample variances are 8.73 and 0.35 respectively for sample 1 and 8.68 and 0.40 respectively for sample 2. Find a 9096 lower-confidence bound on 01/02

Show work The diameter of steel rods manufactured on two different machines is being investigated. Two random samples of sizes ni = 15 and n2-17 are selected. Sample means and variances are x-8.73, s?-0.33,-2-8.68, s?-0.39. Round your answers to two decimal places (e.g. 98.76) (a) Construct a 90% two-sided confidence interval on ?14 (b) Construct a 95% two-sided confidence interval on ? /of: (c) Construct a 90% lower-sided confidence interval ?75
We want to investigate the diameter of steel rods that are manufactured on two different sites. We pick two different random samples of sizes n1 = n2 = 15. The sample means are X1 = 6.2, X2 = 7.8, respectively. The sample variances are s 2 1 = 4 and s 2 2 = 6.25. Assume that both sites produce rods of diameter that is normally distributed with the same standard deviation σ1 = σ2. Answer the following questions. (a)...
