QUESTION:

Problem 37E

Baldness and heart disease Medical researchers followed 1435 middle-aged men for a period of 5 years, measuring the amount of Baldness present (none = 1, little = 2, some = 3, much = 4, extreme = 5) and presence of Heart Disease (No = 0, Yes = 1). They found a correlation of 0.089 between the two variables. Comment on their conclusion that this shows that baldness is not a possible cause of heart disease.

ANSWER:

Step 1 of 2

Since the correlation coefficient is very close to zero, their seems to be no association between Baldness and Heart disease.
