A manufacturer of doorknobs has a production process that is designed to provide a doorknob with a specific target diameter in inches. In an effort to understand the variation in the process currently in place, a random sample of 23 doorknobs produced under the current process indicates a sample standard deviation of 0.025 inch. Construct a 98% confidence interval to estimate the true standard deviation of the diameters of doorknobs manufactured by this firm.
