A question that has puzzled researchers for years is…..do you really sleep worse after watching a horror movie? To answer this question once and for all, a researcher at EUR drew a sample from all visitors to a Horror-film festival (Slasher-fest) in Rotterdam. The participants had to indicate the length of the movie they had watched at the festival, and how many hours they had slept the night after the festival. The researcher also administered a questionnaire to the participants measuring their “degree of anxiety,” and recorded whether a person was male [Gender = 0] or female [Gender = 1].
If you want to know which of the two independent variables (predictors) measured on a different scale [MinuteFilm and Gender] better predicts the number of hours of sleep [HourSleep], TRUE should you look? Give the value of the relevant coefficient of the worst predictor. (3 decimal places)
The correct answer is 0.183
