Use the appropriate t test to analyze the data from the Risky Decisions CogLab. Specifically, evaluate the hypothesis that the mean proportion of risky choices is higher when the choices involve losses than when they involve gains, for large gains/losses and small risks. Use an alpha level of .05, 1-tailed. [8 points]
