Step-by-step explanation:
General Statistics
The results of field studies usually come in the form of a set of numbers that must be organized and analyzed to take useful information out of them. The data provided in the question comes in a two-way frequency table, which we'll reproduce in a more readable format in the figure below.
We are required to calculate the percentage of adults that were taking the supplement and had a cold. By crossing the second row and the second column we get 108 adults were simultaneously taking the supplements and having a cold, thus the required percentage is computed by dividing that quantity by the total of the adults under study:
[tex]\displaystyle \frac{108}{506}=\displaystyle \frac{108}{506}=0.2134[/tex]
It can be said that 21.34% of the adults were taking the supplement and had a cold
