AMU MATH 120 Intro to statistics WEEK 6 lesson CONFIDENCE INTERVALS American Military University

**WEEK 6: CONFIDENCE INTERVALS****Lesson Overview**

In this lesson we will sets and how to construct and interpret confidence intervals**Students will be able to:**- Explain point estimates and margin of error
- Construct Confidence Intervals for a population mean (sigma known or unknown) and population proportion
- Determine the minimum sample size required when estimating the sample mean or proportion
**In this lesson, we will discuss:** - Confidence Intervals

Key Learning Concept - Explain the use and misuse of statistical concepts.
- Employ inferential statistics to analyze sample statistics and relate them to the population.

The following activities and assessments need to be completed this week: - Reading: Understanding Basic Statistics Chapter 8
- Forum 6 – Confidence Intervals
- Homework 6 in WebAssign
- Quiz 3 in WebAssign and complete the critique in the assignment link

**This reading corresponds to the following course objective:**

CO-1. Explain the use and misuse of statistical concepts.

CO-5. Employ inferential statistics to analyze sample statistics and relate them to the population.

**WEEK 6: CONFIDENCE INTERVALS****Assignments, Tests & Quizzes***Instructions:*For the homework, click on the ones you miss and ask for a similar problem until you make a 100. Be sure to study the homework for weeks 5 and 6 for the quiz. The quiz is set for 2 times and takes the best score.- Homework 6 will be completed in WebAssign. WebAssign is interactive and will assist the students in learning the course objectives for the week.
**This assignment corresponds to the following course Objectives:**- Explain the use and misuse of elementary statistical concepts.
- Compute measures of central tendency and measures of dispersion to summarize data collected from real world scenarios.
- Apply inferential statistics techniques to analyze sample statistics and relate them to the population.

Quiz – Quiz 3 Week 6Quiz 3 will be completed in WebAssign. WebAssign quizzes will test the students ability to retain the information on the course objectives for the week.After taking your quiz, go to assignments, Quiz 3 critique and write what you missed. If you did not miss anything then state that you understood everything or that you made a 100. This will need to be completed before your grade is posted.This assessment corresponds to the following course objectives: Explain the use and misuse of elementary statistical concepts.Compute measures of central tendency and measures of dispersion to summarize data collected from real world scenarios.Apply inferential statistics techniques to analyze sample statistics and relate them to the population. |

At the end of this week we should be somewhat familiar with confidence intervals for the mean where sigma is known and where sigma is unknown. Another important topic that will be discussed is confidence intervals for population proportions. Next week lessons include hypothesis testing for the mean where sigma is known and where sigma is unknown.

**Before moving on to the next week, be sure you have completed the following:**

- Reading: Understanding Basic Statistics Chapter 8
- Forum 6 Confidence Interval
- Homework 6 in WebAssign
- Quiz 3 in WebAssign

Next week you will be discussing hypothesis testing for the mean where sigma is known and where sigma is unknown.
