A research organization conducts a survey by randomly selecting adults and asking each, "How do you feel relative to your age?" The results are shown in the figure.

(a) Use a sign test to test the null hypothesis that the proportion of adults who feel older is equal to the proportion of adults who feel younger. Assign a + sign to each adult who responded "older," assign a - sign to each adult who responded "younger," and assign a 0 to each adult who responded "my age." Use \(\alpha=0.05\).

(b) What can you conclude?
