Workplace envy and job performance. Refer to the Academy of Management Journal (August 2019) investigation of whether workplace envy has positive outcomes (e.g., seeking advice seeking from the envied employee). Recall that data collected for 52 sales employees of a cosmetics company were used to fit the model, E(y) = b0 + b1x1 + b2x2 + b3x3, where y = Advice seeking level (7-point scale) x1 = Envy towards fellow worker (7-point scale) x2 = Core self-evaluation (CSE) level (average of 12 7-point scales) x3 = 51 if envied target is a friend, 0 if not6

a. The researchers theorize that both CSE (x2) and friendship (x3) will moderate the relationship between advice seeking (y) and envy (x1). For example, they theorize that the line relating advice seeking and envy will be steeper for workers with a high level of CSE, and steeper if the envied target is a friend. Consequently, the researchers added the interaction terms b4x1x2 and b5x1x3 to the model. Based on this theory, is the value of b4 in the model positive or negative? Is the value of b5 in the model positive or negative?

b. A test of H0: b4 = 0 yielded a two-tailed p@value 6 .01 and bn 4 = .44. What inference can you make from this information?

c. A test of H0: b5 = 0 yielded a two-tailed p@value 6 .05 and bn 5 = .29. What inference can you make from this information?
