{150, 260, 250, n} Which of the following could be the median of the 4 integers listed above?
{150, 260, 250, n}
Which of the following could be the median of the 4 integers listed above?
I. 175
II. 215
III. 235
Answer/Solution
II and III only
Steps/Work
If 175 is the median, (n+250) / 2 = 175. Then n = 100. But n < 150, so 175 can not be the median.
If 215 is the median, (n+250) / 2 = 215. Then n = 180. Thus 215 can be the median.
If 235 is the median, (n+250) / 2 = 235. Then n = 220. Thus 235 can be the median.
The answer is D.
If 215 is the median, (n+250) / 2 = 215. Then n = 180. Thus 215 can be the median.
If 235 is the median, (n+250) / 2 = 235. Then n = 220. Thus 235 can be the median.
The answer is D.
