{130, 280, 250, n}
Which of the following could be the median of the 4 integers listed above?
I. 160
II. 210
III. 250	Select the correct option.
A) I only  B) II only  C) I and II only  D) II and III only  E) I, II, and III
If 160 is the median, (n+250) / 2 = 160. Then n = 70. But n &lt; 130, so 160 can not be the median.   If 210 is the median, (n+250) / 2 = 210. Then n = 170. Thus 210 can be the median.   If 250 is the median, (n+250) / 2 = 250. Then n = 250. Thus 250 can be the median.   The answer is II and III only.
