3) Imagine you conduct a regression study and find that three variables significantly predict workplace self-confidence: The number of months working in position ( = .35), the strength of the relationship with a mentor ( = .15), and the competitiveness of the work environment ( = -.23). a. Which is the strongest predictor and which is the weakest predictor? b. Explain the direction of each relationship between each predictor variable and workplace self-confidence. (Hint: Don't just say "positive" or "negative", but actually explain what the relationship between each two variables means)
