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.

02

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.

Corn variety 1yielded 140bushels per acre last year at a research farm. This year, corn

variety 2, planted in the same location, yielded only 110bushels per acre. Based on these

results, is it reasonable to conclude that corn variety 1is more productive than corn variety

2?

a. Yes, because 140bushels per acre is greater than 110bushels per acre.

b. Yes, because the study was done at a research farm.

c. No, because there may be other differences between the two years besides the corn

variety.

d. No, because there was no use of a placebo in the experiment.

e. No, because the experiment wasn’t double-blind.

Miami's car colorsUsing a webcam, a traffic analyst selected a random sample of 800cars traveling on I-195in Miami on a weekday morning. Among the 800cars in the sample, 24%were white. The margin of error for this estimate is 3.0percentage points.

a. Would you be surprised if a census revealed that 26%of cars onI-195 in Miami on a weekday morning were white? Explain your answer.

b. Explain how the traffic analyst could decrease the margin of error.

A recent random sample of n=805adult U.S. residents found that the proportion who rated the honesty and ethical standards of nurses as high or very high is 0.85. This is 0.15higher than the proportion recorded for doctors, the next highest-ranked profession.

a. Identify the sample and the population in this setting.

b. Do you think that the proportion of all U.S. residents who would rate the honesty and ethical standards of nurses as high or very high is exactly 0.85? Explain your answer.

c. What is the benefit of increasing the sample size in this context?

High-speed Internet Laying fiber-optic cable is expensive. Cable companies want to make sure that if they extend their lines to less dense suburban or rural areas, there will be sufficient demand so the work will be cost-effective. They decide to conduct a survey to determine the proportion of households in a rural subdivision that would buy the service. They select a simple random sample of 5blocks in the subdivision and survey each family that lives on one of those blocks.

a. What is the name for this kind of sampling method?

b. Give a possible reason why the cable company chose this method.

Sealing your teeth- Many children have their molars sealed to help prevent cavities. In an experiment, 120children aged6–8were randomly assigned to a control group, a group in which sealant was applied and reapplied periodically for 36months, and a group in which fluoride varnish was applied and reapplied periodically for 42months. After 9years, the percent of initially healthy molars with cavities was calculated for each group. Identify the experimental units and the treatments.
