Question
e Two samples are selected from the same population. For each of the following, calculate how much dif- ference is expected, on average, between the two sample means. a. One sample has n = 4, the second has n = the pooled variance is 60. b. One sample has n = 12, the second has n = and the pooled variance is 60. c. In part b, the sample sizes are larger, but the pooled variance is enchanged. How does larger sample size affect he magnitude of the standard error for the sample mean difference? 6, and 15, %3D
