Need help with C - H 3 A random sample of 60 patients was selected for an experimental treatment of temporomandibular (jaw) dysfunction (TMD). Prior to treatment, the patients filled out a survey on two nonfunctional jaw habits-bruxism (teeth grinding) and teeth clenching that have been linked to TMD. Of the 60 patients, 4 admitted to only bruxism, 13 admitted to only teeth clenching, 24 admitted to both habits, and 19 claimed they had neither habit. Complete parts a through hbelow.a.
