{"ops":[{"insert":"9.37 A study was conducted to determine if a certain treatment has any effect on the amount of metal removed in a pickling\noperation. A random sample of 100 pieces was immersed in a bath for 24 hours without the treatment, yielding an average of 12.2\nmillimeters of metal removed and a sample standard deviation of 1.1 millimeters. A second sample of 200 pieces was exposed to the\ntreatment, followed by the 24-hour immersion in the bath, resulting in an average removal of 9.1 millimeters of metal with a sample\nstandard deviation of 0.9 millimeter. Compute a 98% confidence interval estimate for the difference between the population means.\nDoes the treatment appear to reduce the mean amount of metal removed?\n\n"}]}
