You are interested in assessing the relationship between watching TikTok and happiness. You survey four of your friends on how many hours they spend watching TikTok per day and find an average of 6.5 hours. You then record their happiness scores that you obtain from a standardized survey that is assumed to have equal intervals throughout the scale, and find an average score 79.25. You obtain the following data from your participants and compute your Pearson's r to be 0.68.
