The percentage of the total population that corresponds to Preference 2 is 47.62%.
We are calculating the percentage of the total population that corresponds to Group A.
To find the percentage of the total population that is part of Group A, we use the formula:
\[\frac{Group\ Count}{Total\ Population} \times 100\]
Substituting the given values, we get \(\frac{36}{63} \times 100\).
The percentage of the total population that corresponds to Group A is 57.14%.
