Take the following as truth: 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. 
Then the following statement: "The other plant has higher production costs because it pays its workers more." is true, false, or inconclusive?
Answer: Inconclusive
