ppose you conduct a study using an independent-measures research design, and you intend to use the independent-measures t test to test whether e means of the two independent populations are the same. The following is a table of the information you gather. Fill in any missing values. Sample 1 Sample 2 Sample Size Degrees of Freedom n1 = 11 n2 = 21 Sample Mean M₁ = 4.5 M2 = 3.6 Standard Deviation S1 = 5.4 e estimated standard error of the difference in sample means for your study is e degrees of freedom for this t statistic is Sums of Squares e 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 cceeding calculations. For the most accurate results, retain these three decimal places throughout the calculations.) SS2 = 1,248.2 et statistic for your independent-measures t test, when the null hypothesis is that the two population means are the same, is
