Problem 3. (20 points) Recall the Allais paradox from lecture. Question 1: ( 1,1) or ( 1,0.89 ; 5,0.10 ; 0,0.01) Question 2: ( 1,0.11 ; 0,0.89) or ( 5,0.10 ; 0,0.90) Most people prefer the first lottery in Question 1 but the second lottery in Question 2. Suppose someone chooses according to prospect theory with value function v(x) = x^0.1 if x >= 0 2x if x<0 where all units are in billions. The probability weighing function they use is pi(p) = sqrt(p) / (sqrt(p) + sqrt(1-p))^2 Show that even without any editing, this can explain the Allais paradox (set reference point to 0 in both questions).

Stories are shared between generations and even between groups of diverse people. This activity asks that you consider why and then apply those ideas to Beowulf. Q1. Based on your reading and any previous knowledge, what do stories (fairy tales in particular) say about the values of a society? Your answer should include at least 1 fairy tale not discussed in this module. Teacher's Note: If you struggle to remember an appropriate fairy tale, Wikipedia has a relatively exhaustive list of fairy tales from across the world. Q2. Now that you have read the excerpts of Beowulf, you will consider two of the following questions. - Question 2A: Is Beowulf a hero? - Question 2B: What can we learn about early British society and values? - Question 2C: How do we compare this story to modern society? - You should add your response and comments to this assignment. - You should indicate which question that you have answered by labeling it and starting a new line with each question. - You will respond in short answer form. Short answer form is a complete paragraph for each question. A complete paragraph is fully developed and includes a stance, reasons and evidence for that stance, and an explanation of why those reasons or pieces of evidence prove your stance. Each short answer responses requires a minimum of one piece of evidence (although to answer the question some may require more). This evidence for this assignment should come from readings from this module and at least 1 other fairy tale. - Be sure to correctly cite your evidence. - Be sure to proofread your response before you reply. This assignment is worth 45 points.
