Q6. Look at the statistical significance for each coefficient B. Are any of your coefficients statistically significant? If so, which ones? (3 points) Q7. Interpret all of your statistically significant coefficients by using the following format: "A 1-unit increase in (X) is associated with a (B)-unit increase/decrease in (Y)." In your interpretation, replace the Y, X, and B with the appropriate variable names and values. For the binary variable of sex, use the following format for your interpretation: "being a female is associated with a (B) unit increase/decrease in (Y)." (6 points) *Note: when interpreting the results, please pay attention to the way the dependent variable is coded (1: very happy, 2: pretty happy, 3: not too happy). That is, as the number increases from 1 to 3, the level of happiness goes down. Q8. Interpret R2. (3 points)
