Dosage Calculations. In Exercise, use the data in the accompanying table, which lists the numbers of correct and wrong dosage amounts calculated by physicians. In a research experiment, one group of physicians was given bottles of epinephrine labeled with aconcentration of “1 milligram in 1milliliter solution,” and another group of physicians was given bottles labeled with a ratio of “1milliliterof a 1:1000 solution.” The two labels describe the exact same amount, and the physicians were instructed to administer 0.12 milligrams of epinephrine. The results were reported in the New York Times.
