Designing the Next Investigative Step
An investigation into a high number of vehicle rollovers reveals a strong correlation: a specific vehicle model equipped with Brand A tires experiences frequent, catastrophic tire failures, while the identical vehicle model equipped with Brand B tires does not. The initial hypothesis is that a defect in Brand A tires is the primary cause. Propose one specific, additional investigation or piece of data you would seek to either strengthen or challenge this initial hypothesis, and briefly explain your reasoning.

Sole Proprietor's Hiring Decision
An investigation into a series of vehicle rollovers revealed a critical pattern: vehicles of a specific model equipped with Firestone tires experienced a significantly high rate of tire blowouts, whereas identical vehicles of the same model equipped with Goodyear tires had a normal failure rate. Based only on this comparative data, what is the most logical initial inference?
Evaluating Evidence in Product Failure
An investigation into a series of vehicle rollovers found that Ford Explorers equipped with Firestone tires had a significantly high rate of tire blowouts. In contrast, identical Ford Explorers equipped with Goodyear tires showed a normal, expected failure rate. A safety analyst concludes that a defect in the Firestone tires was the most probable cause. Based only on this comparative data, which statement best evaluates the analyst's conclusion?
An investigation into a series of vehicle rollovers found that Ford Explorers equipped with Firestone tires had a significantly high rate of tire blowouts, while identical Explorers equipped with Goodyear tires did not. A lawyer representing the tire manufacturer argues, 'This doesn't prove our tires are faulty. It's possible that the drivers who chose our tires were systematically more aggressive or drove in harsher conditions than those who chose the other brand.' Which of the following statements provides the strongest critique of the lawyer's argument?
The Logic of Comparative Analysis
Evaluating a Causal Claim
True or False: The observation that Ford Explorers equipped with Firestone tires had a high rate of blowouts, while identical Explorers with Goodyear tires did not, is sufficient evidence to conclude that the design of the Ford Explorer played no role in the tire failures.
Designing the Next Investigative Step
In an investigation into a series of vehicle rollovers, it was observed that a specific vehicle model had a high rate of tire blowouts when equipped with Brand A tires, but a normal, expected rate when equipped with Brand B tires. From a research design perspective, what is the primary function of including the data from the vehicles with Brand B tires?
