A research has been conducted on independent random samples of undergraduate and graduate graduates who are insurers by making a job change. Average working time of 44 undergraduate graduates before job change is 35.02; sample standard deviation was obtained as 18.20 months. An average of 36.34 in 50 graduate graduates; sample standard deviation was found 18.94 months. Test whether the working averages of the two populations before the job change differ from each other by creating H0 and H1 hypotheses and test the result of α = 0.10 significance
