What do we have on the graph to understand the effect of students taste buds after eating a mint?

Let's review the graph carefully:

1. The relative frequency of guessing the brand of ice tea after eating a mint was 0.2 or 20% and 0.68 or 68% when a student surveyed didn't eat a mint.

2. On the other hand, the relative frequency of guessing the incorrect brand of ice tea was 0.8 or 80% for the group who ate a mint and 0.32 or 32% for the group who did not.

Therefore, after comparing these results we can select the correct statement:

B. Students who did not eat a mint were more accurate guessers.
