Chapter 1: Q 1.100. (page 30)

The Salk Vaccine. In Exercise 1.17 on page 8, we discussed the Salk vaccine experiment. The experiment utilized a technique called double-blinding because neither the children nor the doctors involved knew which children had been given the vaccine and which had been given placebo. Explain the advantages of using double-blinding in the Salk vaccine experiment.

Short Answer

Expert verified
  • lowers the chance of a doctor's biased diagnosis.
  • Help doctors maintain track of such a large number of grade school children.

Step by step solution

01

Step 1. Given information.

The given statement is:

In Exercise 1.17 on page 8, we discussed the Salk vaccine experiment. The experiment utilized a technique called double-blinding because neither the children nor the doctors involved knew which children had been given the vaccine and which had been given a placebo.

02

Step 2. Advantages of using double-blinding in the Salk vaccine experiment.

The benefits of utilizing double-blinding in the Calk vaccination study are as follows:

  1. Such a process aids in entirely randomizing grade-school students, as well as lowering the chance of a doctor's biased diagnosis.
  2. Because the evaluation center is in charge of keeping a track of such a large number of grade school children, such a technique would also lessen the work required by doctors to maintain track of such a large number of them.

In Exercises 1.17-1.22, state whether the investigation in question is an observational study or a designed experiment. Justify your answer in each case.

Do Left-Handers Die Earlier? According to a study published in the Journal of the American Public Health Association, left-handed people do not die at an earlier age than right-handed people, contrary to the conclusion of a highly publicized report done 2 years earlier. The investigation involved a 6-year study of 3800 people in East Boston older than age 65. Researchers at Harvard University and the National Institute of Aging found that the "lefties" and "righties" died at exactly the same rate. "There was no difference, period," said Dr. J. Guralnik, an epidemiologist at the institute and one of the coauthors of the report.

Lobbying Congress. In the special report, "Bitter Pill: Why Medical Bills Are Killing Us" (TIME, Vol. 181, No. 8, 2013), S. Brill presented an in-depth investigation of hospital billing practices that reveals why U.S. health care spending is out of control. One of the many statistics provided in the report is that, during the period from 1998 through 2012, the pharmaceutical and health-care-products industries and organizations representing doctors, hospitals, nursing homes, health services, and HMOs spent \(5.36 billion lobbying Congress.

(a). Under what conditions would the \)5.36 billion lobbying-expenditure figure be a descriptive statistic? Explain your answer.

(b). Under what conditions would the $5.36 billion lobbying- expenditure figure be an inferential statistic? Explain your answer.

Ghost of Speciation Past. In the article, "Ghost of Speciation Past" (Nature, Vol. 435, pp. 29-31), T. Kocher looked at the origins of a diverse flock of cichlid fishes in the lakes of southeast Africa. Suppose that you wanted to select a sample from the hundreds of species of cichlid fishes that live in the lakes of southeast Africa. If you took a simple random sample from the species of each lake and combined all the simple random samples into one sample, which type of sampling design would you have used? Explain your answer.

What are the two major types of statistics? Describe them in detail.

Almost any inferential study involves aspects of descriptive statistics. Explain why.
