Question

a study found that people who suffer from obstructive sleep apnea are at increased risk of having heart disease. identify the two events described in the study. do the results indicate that the events are independent or dependent?

identify the two events. choose the correct answer below.
a. sleep apnea and heart disease
b. study and heart disease
c. study and sleep apnea
d. having sleep apnea and not having it

are the events independent or dependent?
dependent
independent

Explanation:

Identify the two events described in the study

Using the Independent Events Probability and Dependent Events knowledge points

• The study investigates the relationship between "people who suffer from obstructive sleep apnea" and their "risk of having heart disease."
• Therefore, the two core events being analyzed are having sleep apnea and having heart disease.
• This corresponds to option A.

Determine if the events are independent or dependent

Using the Dependent Events knowledge point

• Two events are dependent if the occurrence of one event affects the probability of the occurrence of the other.
• The study states that people who suffer from obstructive sleep apnea are at an increased risk of having heart disease.
• Because having sleep apnea changes (increases) the likelihood of having heart disease, the occurrence of one event affects the probability of the other.
• Thus, the events are dependent.

Answer:

Question 1

• (A) Sleep apnea and heart disease (Correct answer)
• (B) Study and heart disease
• (C) Study and sleep apnea
• (D) Having sleep apnea and not having it

Question 2

• Dependent (Correct answer)
• Independent
