Suppose you have a sample of scores for time on target of a tracking task. In this task, a person must follow a moving target with a mouse on a computer screen. The amount of time the person follows the target during a trial is recorded. The s for the distribu- tion of these scores is 18.0 seconds. a. Find the value of s for sample sizes of 4, 9, and 36. b. What relationship between the value of s and sample size is illustrated by these samples? Suppose you have a sample of scores for time on target of a tracking task.
