Germany gave 33,000 3rd-graders in Saxony a sports club membership voucher in the hopes of improving lifelong fitness. Ten years later, researchers compared those 3rd graders to children in other states and to children in Saxony before the vouchers were given out. Saxony is a dummy variable for if the child lived in Saxony and Cohort is a dummy variable for if the child was in the right cohort to receive the voucher. In order to qualify for the program, students had to be in the right cohort AND living in Saxony. Looking at several outcome variables, the researchers found that: Do they belong to a sports club now? = .144 + .004*Saxony + .008*Cohort + .004*Saxony* Cohort (.019) Weekly hours of sport = .25 + .007Saxony + .001Cohort - 0.069*Saxony*Cohort (.161) Obesity = .12 + .010Saxony + .002Cohort + .005*Saxony* Cohort (0.016) (Standard errors are in parentheses) Which of the following conclusions are correct? O The program did not have a statistically significant effect on sports club membership ten years later O The program reduced weekly sport activity ten years later by 6.9 percentage points, holding all else constant, which was statistically significant O The program did not have a statistically significant effect on weekly activity rates ten years later O The program did not have a statistically significant effect on obesity ten years later O The program increased obesity in Saxony by an amount that is statistically significant but economically irrelevant
