A manufacturer of doorknobs has the production procedure that is designed to provide doorknob with target diameter of 2.5 inches. Historically, the standard deviation of diameter has been 0.035 inch. In an effort to reduce the variation in process, the process was redesigned. A sample of 25 doorknobs produced under new process results in a sample standard deviation of 0.025 inch. At the 0.05 level of significance, is there evidence that the new process significantly reduces the population standard deviation? Assume diameter measurements to be normally distributed.
