The definition of the 25th/75th percentile in this exercise is (I think) slightly different than in the associated video. The video notes that the 25th/75th percentile can be defined either using or not using the median, but then goes on to use the median. If that were done here, the value would be halfway between the 4th & 5th values, but this is marked as wrong (the correct answer in the exercise is the 4th value). Perhaps you should make both answers correct? (or clarify?). It's a great exercise, though--I love it. Thanks.
