People tend to evaluate the quality of their lives relative to
others around them. In a demonstration of this phenomenon,
Frieswijk, Buunk, Steverink, and Slaets (2004) conducted fictitious
interviews with frail elderly people. In the interview, each person
was compared with others who were worse off. After the interviews,
the elderly people reported more satisfaction with their own lives.
A researcher decided to replicate this study. In her study, nine
elderly people completed a life-satisfaction scale. For this
particular scale, . The researcher collected the following data:
20, 17, 22, 23, 19, 25, 27, 21, 25. Is this sample significantly
more satisfied with life than the general population? State whether
a z test or one-sample t test should be used to
analyze the data and why that test should be used.
