During a keynote presentation, the speaker mentions that she is the head of neurology at a major medical center. The speaker then goes on to discuss why wearing helmets is important for bicyclists of all ages. What factor of credibility has the speaker attempted to establish

Competence

Explanation:

Credibility generally has three different types of elements or factors, and includes, competence, compassion, and confidence.

Hence, in this case, when the speaker mentions that she is the head of neurology at a major medical center, she is trying to let the audience understand or know that she is competent or has competency in telling them the dangers involved in not wearing helmets for bicyclists of all ages.
