7. As noted on page 320, when ie tW are equal, the estimated standard error for thhe independent-measures i test provides a measure of how much difference to expect between twO sample means. For each of the following situations, assume that u, should be expected between the two sample means. 2. One sample has n = 8 scores with SS second sample has n b. One sample has n 8 scores with SS the second sample has n = 4 scores with SS = 90. c. În part b, the samples have larger variability (bigger SS values) than in part a, but the sample sizes are unchanged. How does larger variability affect the size of the standard error for the sample mean difference? M2 and calculate how much difference = 45 and the 4 scores with SS = 15. 150 and

7. As noted on page 320, when the two populanon Hedils are equal, the estimated standard error for the independent-measures i test provides a measure of how much difference to expect between twoG sample means, For each of the following situations, assume that i should be expected between the two sample means. 2. One sample has n = second sample has n = b. One sample has n = 8 scores with SS the second sample has n = €. In part b, the samples have larger variability (bigger SS values) than in part a, but the sample sizes are unchanged. How does larger variability affect the size of ihe standard error for the sampie mean difference? l2 and calculate how much difference 8 scores with S3 = 45 and the 4 scores with SS = 15. 150 and 4 scores with SS = 90.
