A manufacturer of fishing equipment conducted a test of its products by giving them to eight fishermen who used them with the following results. Ed and Flo used a Hot Spot lure and caught no fish. Dan and Amy used a Trusty rod with a Husky reel, and Amy caught fish but Dan did not. Jake used a Sure Catch lure, a Best Bet rod, a Spiffy reel, and caught fish. Bill and Tim used a Husky reel, but only Bill caught fish. Kat used a Best Bet rod with a Husky reel and caught fish. Amy and Kat used a Sure Catch lure, but only Kat used monofilament line. Bill used a Trusty rod, monofilament line, and a Sure Catch lure. Flo and Tim used Best Bet rods, and both Tim and Dan used Dynamite lures. Finally, Flo used a Husky reel, Jake and Dan used monofilament line, and Ed used a Spiffy reel on a Trusty rod. What conclusion can the manufacturer draw about the power of this equipment to catch fish? Construct a table that supports this conclusion. Which one of Mill's methods did the manufacturer use? What sense of causality is involved in the conclusion?
