RSMT 1500 Major Lab Assignment
Do the questions/tasks described below.
You may work online in groups of up to 3 people.
Submit the answers/results via Course Messenger on Blackboard, as an attached Microsoft Word document. Make sure the subject line includes the term “Major Lab”.
Only one person from the group needs to submit the document, but make sure that the document has the names of ALL people in the group.
Create a 1-question survey, or think of a single property to measure in the world around you. Whichever you choose, your data must be numerical, such that calculating a mean value would be possible and make practical sense
Survey example: “How many hours of sleep did you get last night?”
Measurement example: Measuring how many minutes of advertising youtube videos have.
For your numerical question or measurement, before you gather any data, come up with a guess as to what the mean value of your data will be.
Introduction
1. What is your survey question/measurement?
2. How would studying this question, or conducting these measurements, benefit science, business, or humanity? If the answer is “It wouldn’t”, then think of a way that it would, or go back to Question 1 and think of a different subject to study. No one will fund a statistical study unless they see a benefit to it.
3. What was your guess for the mean value?
Setup
4. What was the population you sampled?
5. What was your sampling method(s)?
6. What are any biases or limitations that could arise from your sampling method?
Results
7. Collect/Measure 30 data points, and include a table of the data you collected.
8. What is the sample mean of your data?
9. What is the sample standard deviation of your data?
10. What confidence level (90%, 95%, or 99%) do you believe is appropriate for this study? Explain your answer.
11. Construct a confidence interval for the population mean, using the t-distribution and the confidence level that you selected in Question 10.
12. Does your confidence interval include your initial hypothesis for the sample mean?
Conclusions
13. Based on your answer to Questions 12, was your original hypothesis for the sample mean a good guess? Explain your answer.
14. How can the results of this study be used for a practical application? This isn’t the same as Question 2. Now that you have the results of the study, you can be more specific as to how these results can be applied, or what one can learn from them.
15. What future study would you recommend, to advance the goals of this study?
Acknowledgements
16. What individuals, or organizations, would you like to thank, in assisting you in this study?
