presented in Appendix B of the text and in Statdisk, selecting one that corresponds with your chosen life science. Choose a particular variable you would like to explore and use Statdisk to determine if its distribution is approximately normal.
Note. Data Set 5: Passive and Active Smoke in the text does not include normally distributed data and may not be used in this project.
Prepare a 12- to 15-slide Microsoft ® PowerPoint ® presentation that explains confidence intervals in your chosen life science. Imagine that you are responsible for educating first-year college students who are majoring in your chosen life science. Explain to the students how and why confidence intervals relate to their field.
Discuss the following questions:
What is a normal distribution? Describe your example variable and explain why normally distributed data is important in your chosen life science. Show the distribution of your example variable in a Statdiskgenerated image and demonstrate how to calculate the probability of a range of values within this normal distribution.
What is a standard normal distribution? How does it differ from other normal distributions? Convert the normally distributed example variable within your chosen life science to a standard normal distribution. Show this example in a Statdisk-generated image and demonstrate how to calculate the probability of a range of values within this standard normal distribution.
What is a confidence interval? Outline how confidence intervals may be used in your chosen life science. Demonstrate how to define confidence intervals within the normal distribution example variable.
