Question

the options for the last one are yes or no.

Many studies have been done to look at the relationship between heart disease and baldness. In one study, researchers selected a sample of 663 heart disease male patients and a control group of 772 male patients not suffering from heart disease from hospitals in eastern Massachusetts and Rhode Island. Each was asked to classify their degree of baldness. The results are given in the following table. Use these data to answer the following questions. Baldness None Little Some Much Total Yes 251 165 195 52 663 Heart disease No 331 221 185 35 772 Total 582 386 380 87 1,435 The conditional proportions for each degree of baldness are: None:0.431, little: 0.427, some:0.513, much: 0.598 There are six pairwise differences. Which two are the largest? muchvs little much vs none O much vs.some some vs. little some vs. none little vs. none The conditional proportions for each degree of baldness are: None: 0.431, little: 0.427, some: 0.513, much: 0.598 There are six pairwise differences. Which one is the smallest? O some vs. none O little vs. none O some vs. little O much vs little O much vs none O much vs. some 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.

and can you do all please

Answer 1

Solution:

Six paired differences are:

None vs little = 0.004

None vs some = 0.082

None vs much = 0.167

little vs some = 0.086

little vs much = 0.171

some vs much = 0.085

now,

The two which are largest are:

( Much vs none and much vs little )

and,

the one which is smallest is,

little vs none

Yes, the results from the theory based approach valid for the data in this study.

Thank you....!!
