Skills and self-esteem are believed to influence job performance. To investigate this, an experimenter split 14 recent parolees into "high skill and self-esteem" and "low skill and self-esteem" groups. Three months later, employers were asked to rate each parolee’s job performance on a standard test. The following ratings were obtained: High skills/esteem Low skills/esteem 9 6 6 5 3 5 8 4 7 4 7 5 9 6 Using α = .05, test for a significant difference between groups. What is the t statistic and do you accept or reject the null hypothesis?
