Answer:
The first step on this case is order the dataset on increasing way, and after do this we got:
11 14 15 16 17 17 18 19 21
We have a sample size of n =9
And in order to find the 75th percentile we need to find the position for this percentile with this formula:

So then we can conclude that the 75th percentile would be approximately on the 7 position of the dataset ordered and we got:

Step-by-step explanation:
For this case we have the following data:

The length of the video is
5:25 -2:30 -0:30
= 5:25 -3:00
= 2:25
If the second showing starts on time, it will be over at
5:25 +2:25 = 7:50
The second showing is not over by 7:45 even when it starts on time. It will NOT be over by 7:45 when it starts late.
