Take the following as truth: For example, suppose a study estimates that the average WTP for a reduction in mortality risk of 1/100,000 is $50, but that the actual mortality risk reduction resulting from a given pollutant reduction is 1/10,000.
Then the following statement: "If could be estimated that a reduction in mortality risk of 1/100,000 is $50, but the actual reduction may vary." is true, false, or inconclusive?
