You need two recessive alleles (xx). If even one dominant allele is present, the dominant trait will show (Xx or XX will both result in the dominant trait showing). That’s why they’re called dominant traits, because they overpower the recessive traits. In order for a recessive trait to show you must have two recessive alleles.

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:
"People who use social media more than others are more likely to struggle with social skills face to face."
Hope this helps! :)
