Stat 2000, Section 001, Homework Assignment 1 (15 Points)

(1/13/2017 - Due Friday 1/20/2017 by 10:20am)

• 0) Reading: Section 1.1
  
  
• 1) There must be some reason why your department thinks that Stat 2000 is a class you should attend or why you voluntarily attend this class. Describe on about one page what kind of statistical problems and data you might encounter in your future job. What kind of statistical knowledge do you think would be most useful to help you in this job?
  
  
• 2) Please work on the following textbook exercises in Moore/McCabe/Craig:
  
  
  • Exercise 1.7:
    
    
  • Exercise 1.16:
    
    
  • Exercise 1.27:
    
    
  • Exercise 1.33:
    
    
  • Exercise 1.34:
    
    
  • Exercise 1.35:
    
    
• 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.
  
  
  • 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.
  
  

• Please staple your homework submission. Single sheets easily get lost or mixed with other submissions. There will be a grace period of one homework where you get a reminder. Starting with Homework 2, you lose points for homework submissions that are not stapled.
  
  
• Always indicate your full name and A number on homework submissions, quizzes, midterms, and the final. We have some last names that occur 3 or 4 times - and several last names where only one of the letters is different. When you use middle names, nicknames, or just your initials instead of your full first name/last name, we may have problems to award the points to the right student. Whenever we have to look you up due to an incomplete name or missing A number, you will lose points for that submission. Submissions with no name usually result in 0 points for that student :-)
  
  
• Make sure to submit both, your completed homework assignment and quiz, at the same time. Late homework submissions and quizzes that have been taken out of the classroom will not be accepted and count as 0.
  
  
• Recall from the syllabus: Homework will be collected in class in the following week. Homework can also be turned in during the recitation lectures prior to the due date. In general, late homework submissions will not be accepted. If you cannot turn in a homework assignment by yourself, ask a friend to turn in your homework assignment by the due date.
  
  
• Recall from the syllabus: Your homework assignment must be turned in on paper. Electronic submissions via e-mail or through Canvas will not be accepted.
  
  
• Recall from the syllabus: Most of the homework questions will be graded on a done/not done basis. You may get full points for such questions even if your answer is incorrect. It is your responsibility to compare your answers with the solutions that are distributed in the recitation lectures. One or two questions from each assignment will be graded with respect to correctness. You may fully answer such a question, but still receive 0 points in case your answer is totally wrong. It will not be announced in advance which question(s) will be graded with respect to correctness.
  
  
• Recall from the syllabus: A short quiz will be given at the end of each lecture when a homework assignment is due. Make sure to bring a calculator to class on those days! Each quiz will consist of one or at most two short questions that are a direct adaptation of a homework question. While the text of the questions remains the same, and therefore should be recognizable for everyone who worked on the homework assignment, the numbers in the questions will be different. You can answer the quiz with your homework solutions at hand, but you can't use the textbook nor any of the slides from the lecture notes. When you work on your homework answers, make sure to copy relevant formulas for each question onto your answer sheet so you will know how to solve the same question again when it is asked in a quiz (but with different numbers).
