Chapter 1: Q 1.26. (page 9)

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.

Short Answer

Expert verified

Part (a) If the result is produced based on all lobbying expenditures then it will represent a descriptive statistic.

Part (b) If the estimated result is based on a sample of lobbying expenditures then it will represent an inferential statistic.

Step by step solution

01

Step 1. Given information.

The given investigation is:

In the special report, "Bitter Pill: Why Medical Bills Are Killing Us", 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.

02

Part (a) Step 2. Explain under what conditions would the $5.36 billion lobbying-expenditure figure be a descriptive statistic.

Descriptive statistics are those that represent information that has been summarised and structured.

If the result is produced based on all lobbying expenditures made by the pharmaceutical and health-care-products industry and groups from 1998 to 2012, the condition that $5.36 billion lobbying Congress will represent descriptive data.

03

Part (b) Step 1. Explain under what conditions would the $5.36 billion lobbying- expenditure figure be an inferential statistic.

We know that Inferential statistics are statistics that are used to draw conclusions about a population based on a sample of that population.

If the estimated result is based on a sample of lobbying expenditures made by the pharmaceutical and health-care-products industry and groups from 1998 to 2012, the condition that $5.36 billion lobbying Congress will represent the inferential statistics.

Regarding observational studies and designed experiments:

(a) Describe each type of statistical study.

(b) With respect to possible conclusions, what important difference exists between these two types of statistical studies?

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.

Identify two statistical methods other than a census for obtaining information.

Wasp Hierarchical Status. In an issue of Discover (Vol. 26, No. 2, pp. 10-11), J. Netting described the research of E. Tibbetts of the University of Arizona in the article, "The Kind of Face Only a Wasp Could Trust." Tibbetts found that wasps signal their strength and status with the number of black splotches on their yellow faces, with more splotches denoting higher status. Tibbetts decided to see if she could cheat the system. She painted some of the insects ' faces to make their status appear higher or lower than it really was. She then placed the painted wasps with a group of female wasps to see if painting the faces altered their hierarchical status. Was this investigation an observational study or a designed experiment? Justify your answer.
