Assignment 1; Psych 2021 3.0 P Due: Beginning of class on February 25, 2016 (Make sure to show all your work, including your formulas, for all calculations) Total marks: 25 1. Recently on the Comedy Channel a female Canadian comic asked the following question: “When you are out at a bar have you ever noticed that after four or five drinks all the ugly people seem to have gone home?” The premise of her question is that alcohol consumption alters our perception of attractiveness. Imagine that an experimenter wanted to determine if this change in our perception of attractiveness was related to our experience with alcohol. To test this idea s/he collected the following data from 25 experienced drinkers and 25 inexperienced drinkers. Each of the numbers below is the number of drinks (1 ounce shots) required to alter the participant’s perception of attractiveness. Experienced Drinkers: 8, 7, 2, 1, 6, 7, 7, 5, 8, 5, 4, 7, 7, 6, 6, 3, 6, 6, 3, 8, 4, 2, 5, 6, 6 Inexperienced Drinkers: 8, 5, 4, 4, 3, 3, 2, 6, 2, 3, 1, 6, 3, 2, 4, 5, 4, 4, 3, 4, 5, 7, 5, 5, 4 Answer the following four questions based on the data above.
