 * Question 1 - Cough Syrup**: Confidence Intervals. Hopefully the wiki page has enought to figure it out. Is there any special DQE wording that we need to use?


 * Question 2 - Insulating Paper Plymnerization**:

Used Minitab for parts a & b. There are two plots that provide Anderson-Darling values. One is the probability plot under the graph menu that had the confidence interval lines. The other is the Normality Test under Basic Statistics, Stat menu.

Also used MInitab Interval plot for one answer to part c. Can compute using the formula on Slide 68. I'm getting different values for the confidence interval. Wonder what I am doing wrong? Double checked the mean and std deviation using MInitab Display Descriptive Statistics using basic statistices under the Stat menu. The Basic Statistisc Graphical Summary has a table with the CI. **NICE!!** Could have been a time saver.


 * Question 3. Lighting Flashes**


 * Question 4. Metal Arc Welds**


 * Question 5: Light Bulbs**
