An estimate of the standard distance between the difference in sample means (M_1 - M_2) and the difference in the corresponding population means (mu_1 - mu_2) The variance across all the data values when both samples are pooled together A

Fill in any missing values. Sample Size Degrees of Freedom Sample Mean M: -27.6 M2 = 21.5 Standard Deviation Si = 4.5 Sums of Squares n - 21 Sample 1 Sample 2 n2-11 SS2 = 302.5 The pooled variance for your study is (Note: You are being asked for this value to three decimal places, because you will need to use it in succeeding calculations.
