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

Explanation:

Identify the two events

Using the Independent Events Probability and Dependent Events knowledge points

The study states: "A study found that people who suffer from obstructive sleep apnea are at increased risk of having heart disease."

The two distinct occurrences or conditions being observed in the subjects are:

1. Suffer from obstructive sleep apnea.
2. Having heart disease.

Therefore, the two events are sleep apnea and heart disease.

Determine dependence

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 shows that having sleep apnea increases the risk (probability) of having heart disease. Since the probability of having heart disease changes depending on whether a person has sleep apnea, the two events are dependent.

Answer:

• 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
