For each model, answer the following questions: Q5a: Which independent variables were significantly associated with the primary outcome variable at the significance level of 0.05? Q5b: For each model, how many percentages of variance in the primary outcome variable can be explained by the linear regression model? ? Q5c: Which independent variables were significantly associated with the primary
