Question:
Reconsider the data from the study investigating whether people who hold high-power poses are more likely to take risks (such as the double or nothing bet) compared to those who hold low-power poses.
a. Calculate the observed value of the relative risk of taking the bet for those who held high-power poses compared to those who held low-power poses.
b. State your null and alternative hypotheses in the context of relative risk of taking a bet.
c. Use an appropriate randomization-based applet to find a p-value to test whether the observed relative risk (as calculated in part (a)) is statistically significant. Report and interpret the p-value in the context of the study. Note: Make sure to change the statistic to “Relative risk” when using the applet.
d. If you have a p-value from using the difference in conditional proportions as your statistic (from the previous exercise), compare that p-value to the one reported in part (c). Are they close? Explain why that makes sense.
