Cоmpаrisоn оf peаk expirаtory flow rate (PEFR) before and after a walk on a cold winter's day for a random sample of 9 asthmatics. There are two columns, one of PEFR's before the walk and the other of PEFR's after the walk. Subject 1 2 3 4 5 6 7 8 9 Before 312 242 340 388 296 224 391 502 290 After 300 201 232 312 220 236 328 330 231 The following output shows the results of applying the Signed-Rank test to this data. Based on this output, determine which of the following statements are correct interpretations about the difference in the Before and After flow rates. (Select all that apply.)
