Two machines are used for filling plastic bottles with a net volume of 16.0 ounces. The fill volume can be assumed normal, with standard deviation σ1 = 0.020 and σ2 = 0.025 ounces. A member of the quality engineering staff suspects that both machines fill to the same mean net volume, whether or not this volume is 16.0 ounces. A random sample of 10 bottles is taken from the output of each machine.Questions:Find a 95% confidence interval on the difference in means. Provide a practical interpretation of this interval. Assuming equal sample sizes, what sample size should be used to assure that β = 0.05 if the true difference in means is 0.04? Assume that α = 0.05. 16.0316.0416.0516.0516.02MACHINE 116.0115.9615.9816.0215.9916.0215.9715.9616.0115.99MACHINE 216.0316.0416.0216.0116.00
