Final Answer:
The chart or data doesn't specify the percentage of international students in the undergrad population, so none of the given options can be confirmed.
Step-by-step explanation:
Unfortunately, the information regarding the percentage of international students among the undergrad population isn't available in the provided context. Without specific data or a chart illustrating these figures, it's impossible to ascertain the accurate percentage. The options presented (5%, 10%, 15%, 20%) are speculative, as the actual percentage isn't provided or indicated. To accurately determine the percentage of international students, precise data reflecting the composition of the undergrad population would be necessary.
Mathematically calculating the percentage without relevant data would be inaccurate and speculative. Therefore, the most appropriate response in this case is to state the absence of specific information regarding the percentage of international students within the undergraduate population. Without factual data or a specific chart delineating these statistics, confirming any percentage from the options provided would be unsubstantiated. It's essential to rely on accurate and verifiable data to ascertain such statistics.
