7. a pegboard task requires that participants place small metal pegs into a board with holes arranged in rows. normative data show that when people work as fast as possible, the scores are normally distributed, and the mean time to complete the task is µ = 185 seconds with σ = 16. because this task measures hand-eye coordination, the researcher tests a sample of n = 18 participants who have recently been diagnosed with multiple sclerosis (ms). for the sample of participants with ms, the mean completion time is m = 212 seconds. is hand-eye coordination significantly different for those newly diagnosed with ms? use a two-tailed test.
