Question: Factors correlated with job performance. Ladebo and Awotunde (2007) studied many factors possibly related to job performance, including work overload, emotional exhaustion, and self-efficacy (or the belief in one's own abilities). The researchers reported, Job performance was unrelated to emotional exhaustion (r = .03, ns), and [work] overload (r = -.04, ns), but positively related to self-efficacy (r = .22, p)

(a) Which correlation was significant?

(b) Compute the coefficient of determination for the significant correlation.
