Independent random samples of bachelor's and master's degree holders in statistics, whose initial job was with a major actuarial firm and who subsequently moved to an insurance company, were questioned.
For a sample of 44 bachelor's degree holders, the mean number of months before the first job change was 35.02 and the sample standard deviation was 18.20. For a sample of 68 master's degree holders, the mean number of months before the first job change was 36.34 and the sample standard deviation was 18.94. Test, at the 10% level against a two-sided alternative, the null hypothesis that the population mean numbers of months before the first job change are the same for the two groups.
