Role importance for the elderly. Refer to the Psychology and Aging (December 2000) study of the roles that elderly people feel are the most important to them, presented in Exercise 2.10 (p. 35). Recall that in a national sample of 1,102 adults 65 years or older, 424 identified “spouse” as their most salient role. Use a 95% confidence interval to estimate the true percentage of adults 65 years or older who feel that being a spouse is their most salient role. Give a practical interpretation of this interval.
