Statistical Methods for Life and Health Sciences
- (Project_3_1) Use the Neonatal Survival and ECMO dataset to answer the following questions:
Note: The answers to all questions can be calculated by hand, using the Statistics Online Compute Resource SOCR, or, and I do encourage you strongly to, get a hold of and learn at least one statistical package for analyzing such data. Examples are SAS, Splus, R, STATA, SSPS, Excel, SYSTAT and many others. If you do not have access to a computer/proper-software let me know and I'll set you up in the Statistics department computer laboratory.
- Was the proportion of infants with negative BE (acid-base balance in the blood) different from the proportion of infants with positive BE, in this study?
- For the two groups, D & L, are there statistical differences in the IMV levels (ventilation requirements)?
- What is a 95% CI for the ratio of the variances of the the groups (D vs. L) w.r.t. the concentration of oxygen in the blood stream? How do we interpret this CI?
