 gamma (y-hat)  = 0.36 for the relationship between family income (below average, average, above average) and happiness (not happy, pretty happy, very happy). The 95% CI for  gamma (y-hat) is (0.28, 0.44). Interpret both gamma hat (y hat), (would you consider this a strong association, and in what direction?) and the 95% CI for  y (gamma )(be sure to note whether the CI includes 0).
