The original p-value is reported as p < 0.01; the exact p-value is p = 0.000026 based on a z-test of the regression coefficient (regression 1 in Table 8, the coefficient for “Market”; ordered probit regression with group random effects and Huber-White standard errors). The original sample size is 126 participants (54 in the control treatment and 72 in the market treatment). To achieve 90% power the required sample size is 75 participants.
