Refer to the previous exercise about the relationship
between heart disease and baldness. The data are provided in the fi le Heart
Disease And Baldness.
Â a. Compute the conditional proportions of heart disease
given each degree of baldness.
Â b. There are six pairwise differences. Which two are the
largest? Which one is the smallest?
c. Use the Theory-Based Inference applet to compute p-values
and confidence intervals for the two largest differences and the smallest difference.
d. Are the results from the theory-based approach valid for
the data in this study? State the validity conditions and explain how you are
deciding whether or not these conditions are met.
