Question

how can a speaker establish ethos? by noting what jobs or experiences they have that qualify them to speak on a particular subject by listing statistics, research, or data by telling a personal story that will create feelings of sympathy or sadness in an audience by detailing all writers who have had something to say on this topic and then explaining why the speaker thinks differently about it

Explanation:

Ethos is about credibility. Noting relevant jobs/experiences shows expertise (credibility). Listing stats/data is logos (logic). Telling a story for sympathy is pathos (emotion). Detailing writers and differing views is more about argument structure.

Answer:

By noting what jobs or experiences they have that qualify them to speak on a particular subject.
