Solution:Total number of presidents = 1 + 9 + 11 + 14 + 9 = 44
Thus, the median value will be = average of the 44/2 = 22nd president and the 23rd president
Performing the cumulative frequency table (shown in the image attached):
Note: Ideally we should have made a continuous table for the heights by changing the intervals to:
159.5 to 166.5
166.5 to 173.5
173.5 to 180.5
180.5 to 187.5
187.5 to 193.5
However, there is no issue even if we keep the table as given.
We have:
Median value = average of heights between 181 and 187
Thus, the median value must lie between 181 and 187, i.e. only Options B and C are possible
Answer B, C
