Maybe my title is a bit too brief - it is about whether someone is happy about the time spent on a particular app. I can think of two null hypotheses that the second graph alone seems to disprove:

- the amount of time users spend on social media platforms is unrelated to their reported happiness about using said app

- social media apps are not significantly different from phone calls / texts / emails

Those don't need a control group, right?
