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].
Determine to what extent you can predict the amount of hours someone spent partying [HoursPartying] from the amount of minutes that they napped [MinutesNap]. What is the value of the test statistic for the entire model in which you predict hours spent partying [HoursPartying] using amount of minutes spent napping [MinutesNap]? (3 decimals)
The correct answer is 1.102.
