. Identifying a numerical continuous variable to study

Learning Goal: I’m working on a communications project and need support to help me learn.

The project consists of:
1. Finding an interesting problem (No problem related to people will be accepted)
2. Identifying a numerical continuous variable to study
a. For example, for a certain object or process the weight, length, time, volume,
temperature, etc.
3. Gathering data (in a proper manner)
a. Make your best effort to comply with the conditions for the central limit theorem.
b. Show your procedure
4. Making the appropriate calculations
a. Explicitly write or show each one.

5.Creatinga95%Confidence Interval

6. Providing conclusions and recommendations
a. The recommendations are ways to make your project better (or to make it comply).

Also, please Provide powerpoint include :

1. Introduction
2. Methodology
3. Data
4. Calculation, Statistical Analysis, and Conclusion
5. Recommendations

Example:
1. Weight of AA batteries
a. Problem: The variability in weight of randomly selected Energizer© AA batteries
b. Variable: The weight of a single Energizer© AA battery
c. Gather data: Weight randomly selected Energizer© AA batteries (one by one) using a
scale with a readability of at least 0.1 grams (uncertainty +/- 0.05 grams)
d. Evaluate: Check for assumptions (such as normality). Calculate the mean and standard
deviation. Calculate confidence intervals.
e. Conclusion: According to the data… the average weight… a minimum of 14.3 grams…
f. Recommendations: (1) To make sure the data complies with the assumptions I should
have… (2) Using a scale with a readability of 0.01 grams, due to… (3) Improve the
randomness of battery’s selection, because there was problems with… (4) …
