As you get older, going out becomes more of an exhaustion… the mind is willing, but the body is weak. To be able to advise the aging party-goers, a researcher drew a sample out of all the people visiting a certain nightclub in Rotterdam. The participants in the study were asked to report the amount of minutes they napped before going out and to report the amount of hours they spend partying that night. In addition, they had to fill in a questionnaire that quantified their natural need for sleep, and they needed to indicate whether their friends considered them to be a party-animal or a stay-at-home type of person [Group, where stay-at-home = 0 and party animal = 1].
What is the Pearson correlation between the amount of hours spent partying [HoursPartying] and the amount of minutes spent napping [MinutesNap] for stay-at-homes [Group=0]? (3 decimals)
The correct answer is 0.218.
