Homework 17 1 of 13 < > View Policies Current Attempt in Progress -/1 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 x₁ = 8.71, s = 0.35, x₂ = 8.68, s = 0.40, respectively. Assume that o= and that the data are drawn from a normal distribution. (a) Is there evidence to support the claim that the two machines produce rods with different mean diameters? Give bounds on the P-value used to make your conclusion. Use only Table V of Appendix A. P-value Conclusion: Ho
