. Patients on a particular treatment often suffer from anemia. To counter this effect, we think that these patients might be helped if they were given folic acid. To evaluate this, we identify eight patients on the treatment who have been diagnosed with anemia and measure their hematocrit. Then, we give these patients supplemental folic acid for a period of 14 days. Then, we measure their hematocrit again and subtract this second measurement from the initial measurement. Suppose that we observe the following differences: -0.2, 0.5, 0.8, 1.3, 1.4, -5.4, -9.7, -18.2. Create an Excel or R dataset from those values. Calculate the median of those values. Which of the following is closest to that median? A. -4.36 B. -1.35 C. 0 D. 1.35 E. 4.36
