12. GravetterIWallnauchrzano, Essentials Chapter 10 - Endoichapter question 19 Ill'li'hen the populaljon means are equal, the estimated standard error for 1eindependentmeasures t test provides a measure of how much difference to expect between two sample means. For each of the following situations, assume that p: = u: and calculate how much difference should be expected between the two sample means. (Use two decimal places.) One sample has n = 6 scores with 55 = ED, and the second sample has n = 10 scores with 55 = 141]. V One sample has n =5 scores with 55 = 310I and the second sample has n =11] scores with SS = 530. V In line second part of this question, the samples have larger variability {bigger 55 values) than in the rst partI but the sample sizes are unchanged. How does larger variability affect the size of the standard error for the sample mean difference? 0 Larger variability has no effect on standard error. 0 Larger variability produces a smaller standard error. 0 Larger variability produces a larger standard error
