experiment, some subjects from each group had dropped out and the following data were obtained: Control Group Experimental Group nc = 38 nE = 34 X-barc = 75 Sc= 14.5 SE X-barE = 80 = 16.2 a) Test the research hypothesis that the sample means are significantly different from one another (a ≤.05). b) If X-barc is still equal to 75, and both groups' sample sizes and standard deviations remain unchanged, at least how high would X-bare have to be to be considered significantly higher than X-barc (a ≤.05)? c) Suppose both groups' means and standard deviations are unchanged but nc is now 12 and nE is 8. Is X-barE significantly higher than X-barc (a ≤.05)?
