 A research team was interested in whether life satisfaction differed between older (> 65 years old) and younger (18 – 35 year old) adults. Ten individuals of each group were surveyed. The maximum possible score was 60 (high level of satisfaction) and the minimum possible scores was 0 (no satisfaction with life).

older adults:

45 38 52 48 25 39 51 46 55 46

younger adults:

34 22 15 27 37 41 24 19 26 36

 Assume that the research team set α to 0.01 during the design phase of their study.

- Calculate the degrees of freedom

- State  final conclusion for this study based on α and the degrees of freedom, and justify answer.
