Miller walks into a bar. He asks a random sample of patrons how confident they feel (their chances of picking up a member of the opposite sex, measured by subjective probability), and also how many beers they have drunk this evening. His results are shown in the following graph added. a. In his study, what is the independent variable? The dependent variable? How are the two variables related in his data? b. If the average person has drunk 2.5 beers, approximately what does the average person think their chances are of picking up somebody in the bar in this study? c. The regression equation shows a significant beta weight for beer of .41. What is the best interpretation of this estimate?
