Chapter 1: Problem 16

Based on a study of 2,121 children between the ages of 1 and 4 , researchers at the Medical College of Wisconsin concluded that there was an association between iron deficiency and the length of time that a child is bottle-fed (Milwaukee Journal Sentinel, November 26,2005\() .\) Describe the sample and the population of interest for this study.

Short Answer

Expert verified
The sample in this study is the 2,121 children between the ages of 1 and 4 whose data were collected and analyzed. The population of interest includes all children between the ages of 1 and 4 who are being bottle-fed.

Step by step solution

01

Identify the Sample

The sample for this study consists of the 2,121 children between the ages of 1 and 4 whose data was collected and analyzed by the researchers. This is the group from which the data was directly gathered and studied.
02

Identify the Population of Interest

The population of interest refers to the larger group that the researchers want to draw conclusions about. In this context, the population of interest would be all children between the ages of 1 and 4 who are being bottle-fed. The researchers want to study the association between iron deficiency and the length of time a child is bottle-fed in this entire group, not just in the sample.

For each of the statistical studies described indicate whether the study is an observational study or an experiment. Give a brief explanation for your choice. A paper appearing in The Journal of Pain (March 2010 , 199-209) described a study to determine if meditation has an effect on sensitivity to pain. Study participants were assigned to one of three groups. One group meditated for 20 minutes; one group performed a distraction task (working math problems!) for 20 minutes; and one group practiced a relaxation technique for 20 minutes. Sensitivity to pain was measured both before and after the 20-minute session.

A petition with 500 signatures is submitted to a college's student council. The council president would like to determine what proportion of those who signed the petition are actually registered students at the college. There is not enough time to check all 500 names with the registrar, so the council president decides to select a simple random sample of 30 signatures. Describe how she might do this.

Use the following information to answer. Many surgeons play music in the operating room. Does the type of music played have an effect on the surgeons' performance? The report "Death Metal in the Operating Room" (NPR, Dec. 24, 2009, www.npr.org) describes an experiment in which surgeons used a simulator to perform a surgery. Some of the surgeons listened to music with vocal elements while performing the surgery, and others listened to music that did not have vocal elements. The researchers concluded that the average time to complete the surgery was greater when music with vocal elements is played than when music without vocal elements is played. 1.43 Could this experiment have been double-blind? Explain why or why not.

In 2000 , the chairman of a California ballot initiative campaign to add "none of the above" to the list of ballot options in all candidate races was quite critical of a Field poll that showed his measure trailing by 10 percentage points. The poll was based on a random sample of 1,000 registered voters in California. He is quoted by the Associated Press (January 30,2000 ) as saying, "Field's sample in that poll equates to one out of 17,505 voters." This was so dishonest, he added, that Field should get out of the polling business! If you worked on the Field poll, how would you respond to this criticism?
