P correct dose calculation. The probability of a correct dosage calculation given the bottle is labeled with a concentration is 0.

The probability of a correct dosage calculation given the bottle is labeled with a ratio is 0. It appears that the group given the labels with concentrations performed better because the probability of a correct dosage calculation for the bottles labeled with a concentration is much greater tha n the probability of a correct dosage calculation for the bottles labeled with a ratio.

This result suggests that labels with concentrations are much better than labels with ratios. The table below summarizes results from a study of people who refused to answer survey questions.
