Explanation / Answer
Two-Sample T-Test and CI: Job_Apps, Weeks
Two-sample T for Job_Apps vs Weeks
N Mean StDev SE Mean
Job_Apps 12 5.83 2.76 0.80
Weeks 12 5.50 2.43 0.70
Difference = mu (Job_Apps) - mu (Weeks)
Estimate for difference: 0.33
99% CI for difference: (-2.67, 3.34)
T-Test of difference = 0 (vs not =): T-Value = 0.31 P-Value = 0.757 DF = 21
