A researcher conducted a study about the hemoglobin levels among menopausal and non-menopausal women. With study of 20 women total, the following information was collected: Hemoglobin Level (g/dl), Age, and Menopausal Status (yes/no). The researcher conducted a multiple logistic regression analysis to find the effects of hemoglobin level, and age on menopausal status. The summary of the analysis is attached as photo.
Question: Determine the 95% confidence interval for the Odds Ratio for the hemoglobin level with interpretation.
Forensic scientists can learn about events at a crime scene by collecting data. Ex: Properties of
glass shards at a crime scene such as chemical composition can indicate what type of glass was
broken at the scene. Possible types include building glass (building windows or doors), vehicle glass
(car windows or doors), or household glass (lightbulbs, baking dishes).
The fitted logistic regression model for predicting whether a glass shard is building glass based on
sodium is:
=
20.02+(-1.42) (sodium)
1+e20.02+(-1.42) (sodium)
Calculate the log-odds that a glass shard with sodium = 13.08 is building glass.
Ex: 1.23
C
Calculate the probability that a glass shard with sodium = 13.08 is building glass.
