Explanation / Answer

The independent samples t-test tells us that the difference between married people and single people in regard to their level of stress is insignificant. The P-value of t-test in both the cases( where equality of variance is assumed and where equality of variance is not assumed) is greater than 0.05 or even 0.10 .So we have no evidence against the null hypothesis that the that the difference between married people and single people in regard to their level of stress is same.
