Power Poseur Take the following data from Carney et al. (2010), describing the risk-taking behavior of research subjects who did or did not power pose. High-Power Low-Power Total Risky 19 12 31 Safe 3 8 11 Total 22 20 42 Conduct the following hypothesis tests using a = 0.05. Calculate the appropriate statistic, give a P- value, the degrees of freedom if relevant, and the appropriate reject/ fail to reject conclusion. a.) Conduct a two-sample, two-sided hypothesis test with a null of equal proportions. That is, com- pare the proportions prisky for each type of pose (22 VS 20). b.) Conduct a two-sample, one-sided hypothesis test with a null of equal proportions an alternative hypothesis that people taking a high-power pose take more risks. c.) Conduct a x2 test of independence.
