Question

g dosage amounts calculated by 30 physicians. In a research experiment, a group of 16 physicians was given bottles of epinephrine labeled with a concentration of "1 miligram in 1 The tolowing data lists the number of correct and wron militer solution," and another group of 14 physicians was given bottles labeled with a ratio of 1 mililiter of a 1.1000 solution If one of the physicians is randomly selected, ind the probability of getting one who made a correct dosage calcuiabion or was given the bottle with a concentration label Correct Dosage Calculation Wrong Dosage Calculation Concentration Label 14 ("1 miligram in 1 militer solution) Ratio Label C1 militer of a 1.1000 solution") Plphysician made a correct dosage calculation or was given the bottile with a concentration label) (Type an integer or decimal rounded to three decimal places as needed )

Answer 1

P(physician made a correct dosage calculation or was given a bottle with concentration level) = P(physician made a correct dosage calculation) + P(was given a bottle with concentration level) - P(physician made a correct dosage calculation and was given a bottle with concentration level)

                                                         = [(14+3)/30] + [(14+2)/30] - 14/30

                                                         = 19/30

                                                         = 0.633
