My solution: Telephone, Email and Video Conferencing
Telephone:
As you see in the pic I put the times per month for every communication type in an ascending order so the median will fall into the 50%.
Email and Video Conferencing:
Adding the highlighted percentages for 2000 and 2008 for each communication type that n>=1 show that:
2000
E-mail: 10+5+5= 20
Video Conf: 5
2008
E-mail: 20+10+10= 40
Video Conf: 5+5=10
Hence, Email and Video Conferencing is the correct answer.
this was my intitial answer too :S 2nd qn is confusing
