For this exercise, we have a sample of 100 cars driving on a freeway, and the number of occupants in each car was recorded.
00:09
So the number of occupants is the random variable of interest here.
00:15
And the data is shown in this table.
00:17
So we had everything from 1, 2, 3, 4, and 5 occupants in some cars.
00:23
76 of the cars had one occupant, 13 had 2, and so on.
00:28
And we are asked to find the sample median number of occupants.
00:34
And the way to do this is if we ordered our 100 data points from smallest to largest or from largest to smallest.
00:45
So if we did it from smallest to largest, there would be 761s, followed by 132s, followed by 6 3s, and so on.
00:55
The median is the number right in the middle of the dataset...
