Is the New Machine Better? The Medassist Pharmaceutical Company uses a machine to pour cold medicine into bottles in such a way that the standard deviation of the weights is 0.15 oz. A new machine is tested on 71 bottles, and the standard deviation for this sample is 0.12 oz. The Dayton Machine Company, which manufactures the new machine, claims that it fills bottles with lower variation. At the 0.05 significance level, test the claim made by the Dayton Machine Company. If Dayton’s machine is being used on a trial basis, should its purchase be considered?
