Question

The following data lists the number of correct and wrong dosage amounts calculated by 33 physicians. In a research experiment, a group of 15 physicians was given bottles of epinephrine labeled with a concentration of "1 milligram in 1 milliliter solution, " and another group of 18 physicians was given bottles labeled with a ratio of "1 milliliter of a 1:1000 solution." If one of the physicians is randomly selected, what is the probability of getting one who calculated the dose correctly? Is that probability is high as it should be?

Explanation / Answer

P(correct dosage calculation) is given by the sum of all correct calculations in first column =(11+5)/33 = 0.485
