Final answer:
The question asks about the percentage of patients likely to choose an ADA member dentist knowing they follow an ethical code, but the question does not provide the specific percentage mentioned in the survey.
Step-by-step explanation:
The question is asking about the percentage of patients in a 2015 survey by the American Dental Association who stated that they were likely to choose an ADA member dentist knowing that those dentists follow an ethical code.
Unfortunately, the question does not provide the specific percentage mentioned in the survey.
It only gives percentages for other categories like business or nonprofit, other educational institutions, medical school, and independent practice.
Without the specific percentage mentioned in the survey, we cannot provide an accurate answer to the question.
