Can someone help me make a hypotheses?
egoroff_w [7]
Since a hypothesis is a statement rather than a question, you could simply restate the line given to you in line 1.  (That is of course your hypothesis is on the subject of people and social media.)

If I were to make a hypothesis off of that subject I would use something along the lines of:

Hope this helps! :)
