Extracted text: A production process is checked periodically by a quality control inspector. The inspector selects simple random samples of 30 finished products and computes the sample mean product weight . If test results over a long period of time show that 5% of the I values are over 2.1 pounds and 5% are under 1.9 pounds, what are the mean and the standard deviation for the population of products produced with this process? Use z-table. Mean (to 1 decimal) Standard deviation (to 2 decimals)
