Chapter 4: Q 94. (page 260)

The drug manufacturer Merck recently stopped testing a promising new drug to treat depression. It

turned out that in a randomized, double-blind trial, a dummy pill did almost as well as the new drug. The fact that many people respond to a dummy treatment is called

(a) confounding. (d) the placebo effect.

(b) nonresponse. (e) bias.

(c) comparison.

Short Answer

Expert verified

The correct option is (d) the placebo effect.

Step by step solution

01

Given information

In a randomized, double-blind trial, a dummy tablet performed nearly as well as the new medicine.

02

Concept

A placebo is an inactive treatment, sometimes called a 'sugar pill. A placebo (false therapy) is given to a control group in several investigations. This reduces confusion caused by the placebo effect, in which some patients improve because they expect the treatment to work while receiving an inert treatment.

03

Explanation

The drugmaker Merck recently discontinued studying a potential new medicine to treat depression, as stated in the question. The placebo effect refers to the reality that many people respond to a sham treatment. The placebo effect is demonstrated by a dummy that has an impact that is not due to its own features. As a result, option (d) is the proper choice.

Headache relief Doctors identify 鈥渃hronic tension- type headaches鈥� as headaches that occur almost daily for at least six months. Can antidepressant medications or stress management training reduce the number and severity of these headaches? Are both together more effective than either alone? Investigators compared four treatments: antidepressant alone, placebo alone, antidepressant plus stress management, and placebo plus stress management. The headache sufferers named in the following table have agreed to participate in the study.

(a) Outline the design of the experiment. What is this type of design called?

(b) Explain how you would randomly assign the subjects to the four treatment groups. Then carry out your random assignment.

High-speed Internet Laying fiber-optic cable is expensive. Cable companies want to make sure that, if they extend their lines out to less dense suburban

or rural areas, there will be sufficient demand and 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 sample of 5 blocks in the subdivision and survey each family that lives on those blocks.

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

(b) Suppose there are 65 blocks in the subdivision. Use technology or Table D to select 5 blocks to be sampled. Explain your method clearly.

Chocolate and happy babies A University of Helsinki (Finland) study wanted to determine if chocolate consumption during pregnancy had an effect on infant temperament at age of 6 months. Researchers began by asking 305 healthy pregnant women to report their chocolate consumption. Six months after birth, the researchers asked mothers to rate their infants鈥� temperament, including smiling, laughter, and fear. The babies born to women who had been eating chocolate daily during pregnancy were found to be more active and 鈥減ositively reactive鈥濃�攁 measure that the investigators said encompasses traits like smiling and laughter.

(a) Was this an observational study or an experiment? Justify your answer.

(b) What are the explanatory and response variables?

(c) Does this study show that eating chocolate regularly during pregnancy helps produce infants with a good temperament? Explain.

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

(a) a stratified random sample.

(b) every individual selected in an SRS.

(c) every individual in the population.

(d) a voluntary response sample.

(e) a convenience sample.

Sleep debt (3.2)A researcher reported that the average teenager needs 9.3 hours of sleep per night but gets only 6.3hours.17By the end of a 5-day school week, a teenager would accumulate about 15 hours of 鈥渟leep debt.鈥� Students in a high school statistics class were skeptical, so they gathered data on the amount of sleep debt (in hours) accumulated over time (in days) by a random sample of 25high school students. The resulting least-squares regression equation for their data is Sleepdebt铃�=2.23+3.17(days). Do the students have reason to be skeptical of the research study鈥檚 reported results? Explain.
