[answered] Loss of hearing can be a significant problem for older adul


Loss of hearing can be a significant problem for older adults. Although hearing aids can correct the physical problem, people who have lived with hearing impairment often develop poor communication strategies and social skills. To address this problem, a home education program has been developed to help people who are receiving hearing aids for the first time. The program emphasizes communication skills. To evaluate the program, overall quality of life and satisfaction were measured before treatment, again at the end of the training program, and once more at a 6-month follow-up?. Data similar to the results obtained in the study are shown below. Do the data indicate a significant improvement in quality of life following the training program? Test at the 0.05 level of significance.
