12. Positive events are great, but recent research sug- gests that unexpected positive outcomes (e.g., an unseasonably sunny day) predict greater-than-normal amounts of risk-taking and gambling (Otto, Fleming, & Glimcher, 2016). Researchers demonstrated this by comparing lottery sales-indicative of risk-taking-on normal days with lottery sales on days when some unexpected positive event occurred in the city. They observed increased sales after unexpected positive out- comes. Suppose that a researcher extends this observa- tion to the laboratory and randomly assigns partici- pants to two groups. Group 1 receives an unexpectedly large payment for participating and Group 2 receives the expected amount of compensation. The researcher then measures how much money the participants are willing to gamble in a game of chance. Unexpected Positive Outcome n = 16 M = 5.75 SS = 6.5 Expected Outcome n = 16 M = 5.00 SS = 10.0 Test the one-tailed hypothesis that an unexpected Dositive outcome increased the amount of money that
