The Willowbrook and hepatitis Bstudies In the 1960s, children entering the Willowbrook State School, an institution for the intellectually disabled on Staten Island in New York, were deliberately infected with hepatitis. The researchers argued that almost all children in the institution quickly become infected anyway. The studies showed for the first time that two strains of hepatitis existed. This finding contributed to the development of effective vaccines. Despite these valuable results, the Willowbrook studies are now considered an example of unethical research. Explain why, according to current ethical standards, useful results are not enough to allow a study.

Short Answer

Expert verified

The Willowbrook studies are now considered an example of unethical research because they did not protect the participants from harm.

Step by step solution

01

Step 1:Given:The Willowbrook and hepatitis B studies In the 1960s, children entering the Willowbrook State School, an institution for the intellectually disabled on Staten Island in New York, were deliberately infected with hepatitis. The researchers argued that almost all children in the institution quickly become infected anyway. The studies showed for the first time that two strains of hepatitis existed. This finding contributed to the development of effective vaccines. Despite these valuable results, the Willowbrook studies are now considered an example of unethical research.

I have to verify this statement.

Step 2:A situation is given.

The Willowbrook studies are now considered an example of unethical research because they did not protect the participants from harm. New patients who were healthy were subjected to infectious disease. Furthermore, researchers stated that the children would more than likely become infected during their time at Willowbrook.

A TV station wishes to obtain information on the TV viewing habits in its market area.

The market area contains one city of population 170,000, another city of70,000, and

four towns of about 5000residents each. The station suspects that the viewing habits

may be different in larger and smaller cities and in the rural areas. Which of the

following sampling designs would yield the type of information the station requires?

a. A stratified sample from the cities and towns in the market area

b. A cluster sample using the cities and towns as clusters

c. A convenience sample from the market area

d. A simple random sample from the market area

e. An online poll that invites all people from the cities and towns in the market area to

participate.

Doctors and nurses Nurse-practitioners are nurses with advanced qualifications who often act much like primary-care physicians. Are they as effective as doctors at treating patients with chronic conditions? An experiment was conducted with 1316patients who had been diagnosed with asthma, diabetes, or high blood pressure. Within each condition, patients were randomly assigned to either a doctor or a nurse-practitioner. The response variables included measures of the patients' health and of their satisfaction with their medical care after 6months.50

a. Which are the blocks in this experiment: the different diagnoses (asthma, diabetes, or high blood pressure) or the type of care (nurse or doctor)? Why?

b. Explain why a randomized block design is preferable to a completely randomized design in this context.

c. Suppose the experiment used only diabetes patients, but there were still 1316subjects willing to participate. What advantage would this offer? What disadvantage?

When we take a census, we attempt to collect data from

a. a stratified random sample.

b. every individual chosen in a simple random sample.

c. every individual in the population.

d. a voluntary response sample.

e. a convenience sample.

Football on TVA Gallup poll conducted telephone interviews with a random sample of 1000adults aged 18and older. Of these, 37%said that football was their favorite sport to watch on television. The margin of error for this estimate is 3.1percentage points.

b. Explain how Gallup could decrease the margin of error
