Zadanie

A mood tracking app decides to help users understand their mood changes better by also tracking the hours they spend on other applications.
This chart visualizes the results for a video watching app, using a scatter plot to compare each user's hours spent in the app to their mood after exiting the app:
A scatter plot with hours on the x axis and mood on the y axis. The x axis goes from 0 to 4 and the y axis goes from 0 to 10. Both purple and green dots are scattered on the plot. The purple dots start in the upper left corner (e.g. [0.2, 9]) and generally slope down towards the bottom right corner (e.g. [3.5, 2]). The green dots are scattered on the plot for all the the x axis values between the mood values of 6 and 8, seemingly randomly.
Users rate their mood from 1-10, where 1 is least happy and 10 is most happy. The start color #0d923f, start text, g, r, e, e, n, space, d, o, t, s, end text, end color #0d923f represent users that reported using the app primarily for educational videos, and the start color #543b78, start text, p, u, r, p, l, e, space, d, o, t, s, end text, end color #543b78 represent users that reported using it primarily for amusing videos.
Which hypothesis is most consistent with the chart?
