13. Suppose Die research study in the previous problem produced larget variances of 5 - 27 and : - 21 for the twn samples. Assuming that the means and sample sizes are the same as in problem 12, ut the data sufficient to conclude that there Is a significant difference between the two treatmentt? Use h IWO-
mailed test with a = 05. Note how larger vanances affect the outcome of the hypothesis iest. (Again, the two samples are the same size, so the pooled variance is simply the average of the two sample variances )
