People who sustain a concussion or a traumatic brain injury (TBI) are likely to experience sleep problems. Do these problems persist over time? Researchers recruited a sample of 31 patients who had their first TBI 18 months earlier and a control group of 42 otherwise similar individuals without prior TBIs. They compared sleep duration per 24 hours for the 2 groups. Which test is most appropriate for this scenario? A 2-sample test for means B 1-sample z-test for proportion
