identify the two events. choose the correct answer below.

a. having sleep apnea and not having it

b. sleep apnea and heart disease

c. study and sleep apnea

d. study and heart disease

are the events independent or dependent?

dependent

independent

Explanation:

The study is about the relationship between two conditions. The first part asks to identify two events. The problem mentions "people who suffer from obstructive sleep apnea" and "having heart disease", so the two events are sleep apnea and heart disease. For independence, if one event affects the probability of the other, they are dependent. Since the study says sleep apnea increases the risk of heart disease, they are dependent.

Answer:

B. Sleep apnea and heart disease; Dependent
