Resources: Ch. 5 and 6 of the text, the University Library, the Internet, and Statdisk Identify a normally distributed variable related to your chosen life science that serves as your example variable. Review the data sets 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 ĺş? PowerPoint ĺş? 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 Statdisk-generated 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. What is a confidence level? Show how a confidence level relates to the confidence interval using the example variable. What is a critical value? Show how critical values relate to the confidence interval using the example variable.
