This is dealing with parameters and R squared

You are interested in modeling the relationship between (a) the amount of gratitude a person regularly exhibits in their life and (b) the level of the psychological resilience they show in response to negative life events. Let's assume that the model Y = a + bX is an appropriate one for modeling the relationship.
