Question

111 General health survey. The Centers for Disease Control and Prevention (CDCP) in Atlanta, Georgia, conducts an annual survey of the general health of the U.S. population as part of its Behavioral Risk Factor Surveillance System. Using random-digit dialing, the CDCP telephones U.S. citizens over 18 years of age and asks them the following four questions: 1. Is your health generally excellent, very good, good, fair, or poor? 2. How many days during the previous 30 days was your physical health not good because of injury or illness? 3. How many days during the previous 30 days was your mental health not good because of stress, depression, or emotional problems? 4. How many days during the previous 30 days did your physical or mental health prevent you from performing your usual activities? identify the parameter of interest for each question."

Answer 1

The parameter of interest for the four questions in the CDCP general health survey is different for each question. Question 1 asks about the general health status, while questions 2-4 inquire about the number of days in the past 30 days that physical or mental health was not good or prevented usual activities.

Step-by-step explanation:

a. The parameter of interest for question 1 is the general health status of U.S. citizens over 18 years of age. The CDCP wants to know how people rate their own health on a scale of excellent, very good, good, fair, or poor.

b. The parameter of interest for question 2 is the number of days in the previous 30 days that a person's physical health was not good due to injury or illness. This parameter is measured as a numeric answer or one of the options: none, not sure, or refuse to answer.

c. The parameter of interest for question 3 is the number of days in the previous 30 days that a person's mental health was not good due to stress, depression, or emotional problems. This parameter is measured as a numeric answer or one of the options: none, not sure, or refuse to answer.

d. The parameter of interest for question 4 is the number of days in the previous 30 days that a person's physical or mental health prevented them from performing their usual activities. This parameter is measured as a numeric answer or one of the options: none, not sure, or refuse to answer.
