Anonymous? Confidential? Texas A & M, like many universities, offers screening for HIV, the virus that causes AIDS. Students may choose either anonymous or confidential screening. An announcement says, “Persons who sign up for screening will be assigned a number so that they do not have to give their name.” They can learn the results of the test by telephone, still without giving their name. Does this describe anonymous or confidential screening? Why?

Short Answer

Expert verified

This describes both anonymous or confidential screening.

Step by step solution

01

Step: 1:The given statement is:Texas A & M, like many universities, offers screening for HIV, the virus that causes AIDS. Students may choose either anonymous or confidential screening. An announcement says, “Persons who sign up for screening will be assigned a number so that they do not have to give their name.” They can learn the results of the test by telephone, still without giving their name.

I have to tell you the appropriate situation for this question.

02

Step 2:Given:There is a statement above.

This describes anonymous as well as confidential screening.

Reason:

It describes anonymous screening because all individuals are assigned a number, not a name. So it is not possible to find the individual's name from the number alone.

It also describes confidential screening because the identity of subjects or the test result will not be passed along to other individuals.

Sampling gravestones The local genealogical society in Coles County, Illinois, has compiled records on all 55,194gravestones in cemeteries in the county for the years 1825to 1985. Historians plan to use these records to learn about African Americans in Coles County’s history. They first choose an SRS of 395records to check their accuracy by visiting the actual gravestones.

a. Explain how you would use a random number generator to choose the SRS. Your description should be clear enough for a classmate to carry out your plan.

b. Use your method from part (a) to choose the first 3gravestones

Meditation for anxiety An experiment that claimed to show that meditation lowers anxiety proceeded as follows. The experimenter interviewed the subjects and rated their level of anxiety. Then the subjects were randomly assigned to two groups. The experimenter taught one group how to meditate and they meditated daily for a month. The other group was simply told to relax more. At the end of the month, the experimenter interviewed all the subjects again and rated their anxiety level. The meditation group now had less anxiety. Psychologists said that the results were suspect because the ratings were not blind. Explain what this means and how lack of blindness could affect the reported results.

Can a vegetarian or low-salt diet reduce blood pressure? Men with high blood pressure are

assigned at random to one of four diets: (1) normal diet with unrestricted salt; (2)

vegetarian with unrestricted salt; (3) normal with restricted salt; and (4) vegetarian with

restricted salt. This experiment has

  1. one factor, the type of diet.
  2. two factors, high blood pressure and type of diet.
  3. two factors, normal/vegetarian diet and unrestricted/restricted salt.
  4. three factors, men, high blood pressure, and type of diet.
  5. four factors, the four diets being compared.

Kissing the right way According to a newspaper article, “Most people are kissing the

‘right way.’” That is, according to a study, the majority of couples prefer to tilt their heads

to the right when kissing. In the study, a researcher observed a random sample of124

kissing couples and found that 8312466.9%of the couples tilted to the right. To

determine if these data provide convincing evidence that couples are more likely to tilt

their heads to the right, 100simulated SRSs were selected.

Each dot in the graph shows the number of couples that tilt to the right in a simulated SRS

of124couples, assuming that each couple has a 50%chance of tilting to the right.

a. Explain how the graph illustrates the concept of sampling variability.

b. Based on the data from the study and the results of the simulation, is there convincing

evidence that couples prefer to kiss the “right way”? Explain your answer.

A simple random sample of 1200 adult Americans is selected, and each person is asked

the following question: “In light of the huge national deficit, should the government at this

time spend additional money to send humans to Mars?” Only 39% of those responding

answered “Yes.” This survey

a. is reasonably accurate because it used a large simple random sample.

b. needs to be larger because only about 24 people were drawn from each state.

c. probably understates the percent of people who favor sending humans to Mars.

d. is very inaccurate but neither understates nor overstates the percent of people who favor

sending humans to Mars. Because simple random sampling was used, it is unbiased.

e. probably overstates the percent of people who favor sending humans to Mars.
