Question

A study described an experiment that randomly assigned participants to receive $3 to spend on themselves (self-interest), or to receive $3 to donate to a nonprofit charity (imposed charity), or to receive $3 that they could either spend on themselves or donate to charity (choice). After receiving or donating the money, the participants rated how happy they were with this experience, on a seven-point scale (with 1 = not at all, 7 = an extreme amount). The authors reported a significant effect (F ∗ = 9.08, P < 0.001), with follow-up t-tests confirming their hypothesis that imposing self-interest increases outcome happiness. For their analysis, identify the response variable, the explanatory factor, and the hypothesis tested to yield the reported F statistic and P-value.

Answer 1

Explanation: rightarrow The response variable is the study described in an experiment that randomly assigned participants to receive S3 to spend on themselves (self-interest), or to receive S3 to donate to a nonprofit charity (imposed chanty), or to receive S3 that they could either spend on themselves or donate to chanty (choice). rightarrow The explanatory variable is the seven point scale(1 -not at all)(7-an extreme amount.) rightarrow The hypothesis is tested is imposing self interest increases to report F - statistic an p - value to carry the analysis.
