Dr. Guidry conducts a study examining the relationship between the number of friends one has and the experience of daily stress and life satisfaction. She randomly samples 1,500 elderly men and women in Nashville, Tennessee (the state capital), located in the southern United States. Below are her findings.
•Life satisfaction and experience of daily stress: r =.57 (p = .01)
•Number of friends one has and experience of daily stress: r = .09, not sig.
•Number of friends one has and life satisfaction: r = .36 (p = .04)
Considering Dr. Guidry's study, her results could most safely be generalized to which of the following groups?
A)People in the southern United States
B)Elderly people
C)People with a high number of friends
D)People with high life satisfaction

Dr. Guidry's study specifically sampled elderly men and women in Nashville, Tennessee, so her findings can be generalized to this group. It would not be safe to generalize to people in the entire southern United States, as the sample only comes from one city. Additionally, the study did not find significant results for the relationship between number of friends and experience of daily stress, so it would not be appropriate to generalize to people with a high number of friends. Finally, while the study found a significant correlation between number of friends and life satisfaction, it is not clear if this relationship is causal or if it would generalize to people with high life satisfaction in general.
