  • Exercise 1.10, 1.13, 1.19, 1.23, 1.24, 1.25 (3 points each)
    
    
• 3) Below are the data from a "Major" survey from a Stat 2000 class in Spring 2000. Manually construct a bar chart and a pie chart from these data. Provide meaningful labels, headings, and any other relevant information (e.g., what is "Other"?). Rearrange the data first to obtain the best visual effect. (6 points)
  
  
  • Geography: 9
  • Public Health Nutrition: 3
  • Environmental Studies: 14
  • Forestry: 3
  • Recreation Resources Management: 4
  • Anthropology: 2
  • Other: 6
  
  Overall, 41 students indicated their major. "Other" includes one student from each of the following fields: Range Management, Fisheries & Wildlife Management, History, Animal Science, Liberal Arts, and Ag Systems.
  
  
• 4) Recitation Problems (RPs): The following RPs will be discussed during the recitation lectures next week:
  
  Exercise 1.14 (0.5 points), 1.15 (0.5), 1.17 (0.5), 1.18 (0.5), 1.21 (0.5), 1.22 (0.5)
  
  In case you have to miss both of the recitation lectures, you can individually work on these RPs and turn them in together with your regular homework. It is not possible to combine points from attending a recitation lecture and from working on the RPs in a particular week. Full points are awarded when a RP question has been solved entirely, i.e., all parts. It does not matter whether your answer is correct or not. You get points for attempting to solve each problem part. But, you really should try to attend the recitation lectures whenever possible.
