If you have three variables A, B, C and you want to test whether the hypothesis is that everyone focuses on C, can the expected outcome in a chi-square goodness of fit test then be A: 0 B:0 and C: 100 (or whatever sample size you have) ?
I did my survey in line with the problems in the paper of Heath, Larrick, Wu "Goals as Reference Points" (they take prospect theory value function as an explanation for why people work harder with high goals than low goals i.e. loss aversion and diminishing sensitivity). Here one example where I'm not sure how they statistically tested this:
Charles and David both follow workout plans that usually involve doing 25 sit-ups.
One day Charles sets a goal of performing 30 sit-ups. He finds himself very tired after performing 34 sit-ups and, at most, has the energy to perform 1 more.
David sets a goal of performing 40 sit-ups. He finds himself very tired after 34 sit-ups and, at most, has the energy to perform 1 more.
Who will work harder to perform the 35th sit-up?
N=73; Charles: 18% and David: 82%
Then they state: Our subjects reliably predicted that David would exert more effort than Charles (p < .001 by Chi Square). (due to loss aversion of the prospect theory value function)
How did they get the p-value? They don't state this in the paper but they practically say that since 82% chose Davide this implies that loss aversion takes places and people work harder when they are below the goal. I need to prove this similarly but don't know how.
