Unformatted text preview: 4. An independent-measures research study includes the following two samples: Sample 1: n = 20, SS = 128, M = 20 Sample 2: n = 20, SS = 100, M = 10 Then the value of the pooled variance, estimated standard error, and t statistic are __________. 2 5. An independent-measures experiment uses one sample with n = 110 and a second sample with n = 220 to compare two experimental treatments. The t statistic from this experiment will have degrees of freedom equal to __________. 6. What is the value of M D for the following set of difference scores? Scores: 40, 70, 70, 30, 30 ____________________________________ 7. What is the value of the estimated standard error for the following set of D-scores?
