Hearing loss in senior citizens. Audiologists have developed a rehabilitation program for hearing-impaired patients in a Canadian home for senior citizens. (Journal of the Academy of Rehabilitative Audiology, 1994.) Each of the 30 residents of the home were diagnosed for degree and type of sensorineural hearing loss, coded as follows: 1 = hearing within normal limits, 2 = high-frequency hearing loss, 3 = mild loss, 4 = mild-to-moderate loss, 5 = moderate loss, 6 = moderate-to-severe loss, and 7 = severe-to-profound loss. The data are listed in the accompanying table. Use a graph to portray the results. Which type of hearing loss appears to be the most prevalent among nursing home residents?
