  1. 1. B. Heard (These may not be copied, reproduced, or posted in an online classroom without my permission.Students may download one copy for personal use.)
  2. 2.  Week 4 iLab  9 Questions (some requiring multiple answers)  I will show similar problems, but please note these are not the same values!  Submit in the given Microsoft Word Document to the Week 4 iLab Dropbox found in the Dropbox area (tabs at top of your course)
  3. 3.  Number 1  I will be using 1/5, 2/5 and 4/5 (NOT ¼ , ½ and ¾ )
  4. 4.  Now Graph All Three
  5. 5.  Number 2 Download Data (if you haven’t already)  File >> Open Worksheet  Change Drive to pshop$(ilabss)(G:)  Select Math 221 Folder  Select Math221_LabData Minitab  When pop-up shows click “OK” (maybe twice)
  6. 6.  Number 3
  7. 7.  Number 3 ETC
  8. 8.  Number 4
  9. 9.  Forthe first one, x ≥ 1, you would add all of the probabilities from 1 through 10 for 2/5 or calculate 1 – P(0)
  10. 10.  Forthe second one, x > 1, you would add all of the probabilities from 2 through 10 for 2/5 or calculate 1 – (P(0)+P(1))
  11. 11.  Forthe third one, 4<x ≤ 7, you would add all of the probabilities from 5 through 7
  12. 12.  For the last one, x < 4 OR x ≥ 7, you would add all of the probabilities from 0 through 3 AND all probabilities from 7 through 10 (OR YOU COULD SAY 1 – THOSE NOT INCLUDED)
  13. 13.  Number 5Mean = 10 (2/5) = 4 Std Dev = Sq Root (10)(2/5)(3/5) = 1.549
  14. 14.  Number 6Mean = 10 (1/5) = 2 Std Dev = Sq Root (10)(1/5)(4/5) = 1.265
  15. 15.  Number 7Mean = 10 (4/5) = 8 Std Dev = Sq Root (10)(4/5)(1/5) = 1.265
  16. 16.  Number 8 USE DEFINITION OF BINOMIAL DISTRIBUTION…..
  17. 17.  Number 9USE YOUR RESULTS FROM THE SURVEY DATA IN NUMBER 2 ANDCOMPARE THEM TO THE RESULTS FOR ½ IN NUMBER 5. EXPLAINWHY THEY DIFFER (HINT: ONE IS _________ AND THE OTHER IS______________) ABOUT A PARAGRAPH
