The fоllоwing results were оbtаined in а correlаtional study exploring the relationship between locus of control (LoC) and self-esteem scores (SES). Researchers were interested in the nature of the relationship and whether LoC was a reliable predictor of SES scores. N = 120 LoC mean = 16.58 LoC standard deviation = 5.67 SES mean = 23.91 SES standard deviation = 9.22 r = -0.73 r2 = 53.29% 1 - r2 = 46.71% b = -1.19 a = 43.64 Based on these results, match the following (2 points each):
