Premise: The other plant (the  quick-line  plant) has production costs that are 10 percent higher than for the regular line, but the manufacturing lead time from the time a production order is placed until a shirt is available in finished goods inventory is two weeks, compared to eleven weeks for the plant with the  regular line.

Hypothesis: The other plant has low production costs but sends out the product to the distribution center at random intervals.
Relation: contradiction
