A mixture of benzene, toluene, and xylene enters a two-stage distillation process where some of the componentsare recovered. The distillation process operates at steady-state conditions with operating information as shown inthe table. In addition, the following information is known about the distillation process:
98.0% (by weight) of the xylene that enters Column A in the feed stream (Stream 1) leaves in the intermediate stream (Stream 3)
96.0% (by weight) of the benzene that enters in the feed stream (Stream 1) leaves in the top stream from Column B (Stream 4)
Find a set of independent equations that canbe solved for all the unknowns. Clearly identify
the unknowns and identifyyour equations. Solve for the unknowns.

An analyst counted 17 A/B runs and 26 time series observations. Do these results suggest that the data are nonrandom? Explain
This term sometimes is applied to the model for explaining the differences found between naturally happening groups which are greater than those observed on some previous occasion;
