A study is to be made of the relative effectiveness of two kinds of cough medicines in increasing sleep.Six people with colds are given medicine A the first night and medicine B the second night. Their hoursof sleep each night are recorded. The data are:The sleeping hours for people who took medicine A is:4.8, 4.1, 5.8, 4.9, 5.3 and 7.4.And the sleeping hours for the same people but who took medicine B is:3.9, 4.2, 5, 4.9, 5.4, and 7.1To test whether the data indicate significant difference in effectiveness of the two medicines theappropriate test to use isO a.

Please see below. Only given one attempt at this. 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 proportions C 2-sample test for proportions D matched-pairs E 1-sample t-test for means
