Also an analysis will be done after forming confidence intervals based on data formed. Summary statistics: The table below mentioned contains all the relevant…show more content…

So in the alternative either the grade is improved or not because it cannot be the same as before. H0: μ1- μ2 ≤ 0 Ha: μ1- μ2 > 0 Level of significance=0.05 Results: Samples | T statistic | P-value | Matched | 1.81 | 0.04 | Independent | 1.68 | 0.05 | Conclusion: In both the cases there is sufficient evidence to reject the null hypothesis because p-value is either equal to and less than the level of significance and this evidence supports the
