Right, we're told there are six people in an elevator.
00:05
The sum of all of their ages is 190 and their median age is 22.
00:13
So as we think about this, we have these three amounts.
00:17
We know our median rate in the middle is 22 and we know the sum of all of these ages is 190.
00:29
Okay, the names of the people in the elevator are ashish, brooke, kalista, deepak, anid and freya.
00:35
The elevator stops and anish and anid get off.
00:40
The mean or average of the remaining four people is then 30.
00:46
Keep in mind for the sake of argument with the first six, the average age is 31 and 2 .3.
00:58
All right.
00:59
Then as we look at this second situation, we say ashish and anid get off.
01:07
Notice we still have two below this median and two above.
01:11
C and d are still used to determine this.
01:14
So this is the median yet again of these four remaining people...
