1. When operating properly, a chemical plant has a daily production rate that is normally distributed with a mean value of 880 tons/day and a standard deviation of 21 tons/day. During an analysis period, the output is measured with random sampling for 50 days and the mean output was found to be 871 tons/day. With a 95% confidence level, determine if the plant is operating properly.
