What is the value of Σ(X + 1) for the following scores?  Scores: 1, 0, 1, 4

Two samples from the same population both have M = 84 and s2 = 20; however, one sample has n = 10 and the other has n = 20 scores.  Both samples are used to evaluate a hypothesis that µ = 80 and to compute Cohen’s d.  How will the outcomes for the two samples compare?
