Take the following as truth: In practical terms, this means that a retailer carrying a broader array of goods faces increased costs both for carrying goods in inventory that will not sell (overstocks) and running out of a good that sells beyond expectations (stock-outs).
Then the following statement: "This means a retailer that carries a broad array of goods has increased costs by 40%" is true, false, or inconclusive?
Answer: Inconclusive
