This document provides instructions for students to complete a Week 4 lab assignment in their statistics course. It outlines 9 questions for the lab work, with the professor providing guidance and examples for each question. The questions involve graphing and calculating probabilities for different distributions, analyzing survey data using binomial and normal distributions, and comparing experimental results to theoretical probabilities. Students are asked to submit their work and solutions in a Microsoft Word document.

- 17. Week 4 Lab LectureFor the first one, x ≥ 1, you would add all of the probabilities from 1 through 10 for 2/5 or calculate 1 – P(0)
- 18. Week 4 Lab LectureFor the 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))
- 19. Week 4 Lab LectureFor the third one, 4<x ≤ 7, you would add all of the probabilities from 5 through 7
- 20. Week 4 Lab LectureFor 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)
- 21. Week 4 Lab LectureNumber 5Mean = 10 (2/5) = 4 Std Dev = Sq Root (10)(2/5)(3/5) = 1.549
- 22. Week 4 Lab LectureNumber 6Mean = 10 (1/5) = 2 Std Dev = Sq Root (10)(1/5)(4/5) = 1.265
- 23. Week 4 Lab LectureNumber 7Mean = 10 (4/5) = 8 Std Dev = Sq Root (10)(4/5)(1/5) = 1.265
- 24. Week 4 Lab LectureNumber 8USE DEFINITION OF BINOMIAL DISTRIBUTION…..
- 25. Week 4 Lab LectureNumber 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
