We failed to reject our null hypothesis at any reasonable level of significance because our P-value is much greater than Alpha (0.94).  Therefore, there is insufficient evidence to say that the true mean grade point average from students from single-parent households differs from the true mean grade point average from students from two or more parent households.

       In a test for male versus female Grade Point Average, where our null hypothesis was there is no difference between the two genders and our alternative hypothesis was that there is a difference in the means between the two genders.  We rejected the null hypothesis at the 0.05 level of significance because our p-value was less than Alpha.  Therefore, we have sufficient evidence to say that there is a difference in the true mean grade point average between males and females.
