A production process is checked periodically by a quality control inspector. The inspectorselects simple random samples of 30 finished products and computes the sample meanproduct weights x. If test results over a long period of time show that 5% of the x valuesare over 2.1 pounds and 5% are under 1.9 pounds, what are the mean and the standarddeviation for the population of products produced with this process?
