Chapter 2: Problem 15

During the previous calendar year, a county's small claims court processed 870 cases. Describe how a simple random sample of size \(n=50\) might be selected from the case files to obtain information regarding the average award in such cases.

Short Answer

Expert verified
A simple random sample can be selected by numbering the 870 cases from 1 to 870 and then using a random number generator or a table of random numbers to choose 50 distinct numbers within this range. The cases associated with these numbers form the sample.

Step by step solution

01

Understand the Population

In this case, the population comprises 870 cases processed by a county's small claims court. The task requires to pull a simple random sample from this population.
02

Determine the Sample Size

The given exercise states that a simple random sample of size n=50 should be selected. This means that 50 cases need to be selected from the pool of 870 cases.
03

Conduct the Sampling

To select a simple random sample, each of the 870 case files should be assigned a unique number from 1 to 870. Then, use a random number generator or a table of random numbers to select 50 distinct numbers within this range. The cases corresponding to the 50 selected numbers constitute the simple random sample.

Fruit Juice May Be Fueling Pudgy Preschoolers, Study Says" is the title of an article that appeared in the San Luis Obispo Tribune (February 27, 2005). This article describes a study that found that for 3 - and 4-year-olds, drinking something sweet once or twice a day doubled the risk of being seriously overweight one year later. The authors of the study state Total energy may be a confounder if consumption of sweet drinks is a marker for other dietary factors associated with overweight (Pediatrics, November 2005 ). Give an example of a dietary factor that might be one of the potentially confounding variables the study authors are worried about.

The following is from an article titled "After the Workout, Got Chocolate Milk?" that appeared in the Chicago Tribune (January 18,2005\()\) : Researchers at Indiana University at Bloomington have found that chocolate milk effectively helps athletes recover from an intense workout. They had nine cyclists bike, rest four hours, then bike again, three separate times. After each workout, the cyclists downed chocolate milk or energy drinks Gatorade or Endurox (two to three glasses per hour); then, in the second workout of each set, they cycled to exhaustion. When they drank chocolate milk, the amount of time they could cycle until they were exhausted was similar to when they drank Gatorade and longer than when they drank Endurox. The article is not explicit about this, but in order for this to have been a well-designed experiment, it must have incorporated random assignment. Briefly explain where the researcher would have needed to use random assign in order for the conclusion of the experiment to be valid.

In many digital environments, users are allowed to choose how they are represented visually online. Does how people are represented online affect online behavior? This question was examined by the authors of the paper "The Proteus Effect: The Effect of Transformed Self-Representation on Behavior" (Human Communication Research [2007]: 271-290). Participants were randomly assigned either an attractive avatar (a graphical image that represents a person) to represent them or an unattractive avatar. a. The researchers concluded that when interacting with a person of the opposite gender in an online virtual environment, those assigned an attractive avatar moved significantly closer to the other person than those who had been assigned an unattractive avatar. This difference was attributed to the attractiveness of the avatar. Explain why the researchers would not have been able to reach this conclusion if participants had been allowed to choose one of the two avatars (attractive, unattractive) to represent them online. b. Construct a diagram to represent the underlying structure of this experiment.

The article "Television's Value to Kids: It's All in How They Use It" (Seattle Times, July 6,2005 ) described a study in which researchers analyzed standardized test results and television viewing habits of 1700 children. They found that children who averaged more than 2 hours of television viewing per day when they were younger than 3 tended to score lower on measures of reading ability and short-term memory. a. Is the study described an observational study or an experiment? b. Is it reasonable to conclude that watching two or more hours of television is the cause of lower reading scores? Explain.

A novel alternative medical treatment for heart attacks seeds the damaged heart muscle with cells from the patient's thigh muscle ("Doctors Mend Damaged Hearts with Cells from Muscles," San Luis Obispo Tribune, November 18,2002 ). Doctor Dib from the Arizona Heart Institute evaluated the approach on 16 patients with severe heart failure. The article states that "ordinarily, the heart pushes out more than half its blood with each beat. Dib's patients had such severe heart failure that their hearts pumped just 23 percent. After bypass surgery and cell injections, this improved to 36 percent, although it was impossible to say how much, if any, of the new strength resulted from the extra cells." a. Explain why it is not reasonable to generalize to the population of all heart attack victims based on the data from these 16 patients. b. Explain why it is not possible to say whether any of the observed improvement was due to the cell injections, based on the results of this study. c. Describe a design for an experiment that would allow researchers to determine whether bypass surgery plus cell injections was more effective than bypass surgery alone.
