• Confidence Interval 
• Confidence Interval for the mean, sigma known
• Estimate Population Proportion

After reading required for this week study material, 

let's discuss following topics.

1. Why do we need inferential statistics?
2. What is Confidence Interval and how to find it?
3. How Confidence Interval depends on Confidence Level?
4. Give an example of finding Confidence Interval for Population Mean.
5. Show that you can use t-Distribution table. Select any Sample Size,
6. Confidence Level and find t-value from t-Distribution table. 
7. Use columns for Area in Two Tails (estimate procedure is always Two-Tails test).
