Choose the correct dotplot below. O A. OB. O c. 6 8 10 12 14 16 18 6 8 10 12 14 16 18 6 8 10 12 14 16 18 Acute Postoperative Days Acute Postoperative Days Acute Postoperative Days b. Use the result from part (a) to compare the two data sets. O A. The number of acute postoperative days is, on average, less with the static system than with the dynamic system. However, the static system produces more variation in the number of days. O B. The number of acute postoperative days is, on average, less with the dynamic system than with the static system. However, the dynamic system produces more variation in the number of days. O C. The number of acute postoperative days is, on average, less with the dynamic system than with the static system. Also, the static system produces more variation in the number of days O D. The number of acute postoperative days is, on average, less with the static system than with the dynamic system. Also, the dynamic system produces more variation in the number of days.
