Researchers investigating social priming and cooperative behavior conducted a study where participants were primed with either cooperative or neutral words before playing a game. They performed a chi-squared test on the data in Table 1 and obtained a calculated/observed χ2 \chi^2\,χ2 value of 4.15 for a two-tailed (non-directional) test at the 5% level of significance with df=1df = 1df=1.
| Priming Condition | Cooperated | Did not cooperate |
|---|---|---|
| Cooperative Priming (N = 40) | 27 | 13 |
| Neutral Priming (N = 40) | 16 | 24 |
| Level of significance for a one-tailed test | 0.10 | 0.05 | 0.025 | 0.01 | 0.005 |
|---|---|---|---|---|---|
| Level of significance for a two-tailed test | 0.20 | 0.10 | 0.05 | 0.02 | 0.01 |
| df = 1 | 1.64 | 2.71 | 3.84 | 5.41 | 6.64 |
Explain what this calculated value shows in terms of the cooperative behavior of the participants in the study.
