Chi-square test for independences of attributes. 

Friedman and Roseman (1974) have suggested that personality type is related to heart disease. Specifically, type A people, who are competitive, driven, pressured, and impatient, are more prone to heart disease. On the other hand, type B individuals, who are less competitive and more relaxed, are less probable to have heart disease. Suppose that an investigator would like to examine the relationship between personality type and disease. For a random sample of individuals, personality kind is assessed with a standardized test. These individuals are then examined and categorized as to whether they have a heart disorder. The observed frequencies are as follows:

 

 

No Heart Disease

Heart Disease

 

Type A

32

18

50

Type B

128

22

150

 

160

40

 

 Is there a relationship between personality and disorder? Test at .05 level of significance.
