In the commercial production of sugar (sucrose), the product crystais are washed and centrifuged to partial dryness. The crystals are then sent through a rotary dryer where they are contacted with a hot stream of air that reduces the moisture content from 1.10wt% to 0.100wt% The ratio of wet sugar to inlet air fed to the dryer is 3.00kg wet sugar/kg inlet air. The inlet air contains 1.90 mole\% water. Samples of the product crystals are analyzed routinely for water content. The mass fractions of water in the samples on successive days of operation are shown in the following table. The quality of the product during these days of operation has been graded acceptable, and it is decided that the process will be shut down for maintenance when the measured value of xw is more than three standard deviations from the mean of this series of runs. What are the maximum and minimum values of xw allowed without prompting a shutdown?
