Does the salary of human resource managers depend on the sex - Research Paper Example This test shall assume equal variances in the hypothesis testing whereby 95% confidence level and a pooled standard deviation shall be considered. The critical value is a two-tail test which will form the rejection regions.This test shall assume equal variances in the hypothesis testing whereby 95% confidence level and a pooled standard deviation shall be considered.

Since the absolute calculated t value is less than the critical, we fail to reject the null hypothesis of the test. Thus, we can conclude that at 5% level of significance, the mean salary for female human resource directors is equal to the mean salary for male human resource directors. Moreover, as much as the means for the two independent samples are literary, not equal, the t-test has statistically proven that female human resource managers’ salaries are not different from that of male human resource managers.
