Short Answer

Describe the unethical behavior, if any, in each example and describe how it could impact the reliability of the resulting data. Explain how the problem should be corrected. A study is commissioned to determine the favorite brand of fruit juice among teens in California.

  1. The survey is commissioned by the seller of a popular brand of apple juice.
  2. There are only two types of juice included in the study: apple juice and cranberry juice.
  3. Researchers allow participants to see the brand of juice as samples are poured for a taste test.
  4. Twenty-five percent of participants prefer Brand X, 33% prefer Brand Y and 42% have no preference between the two brands. Brand X references the study in a commercial saying "Most teens like Brand X as much as or more than Brand Y."

  1. A seller of a popular brand of apple juice surveying will lead to a biased result, instead, a person unassociated must do the survey.
  2. Limiting to only two types of brands would be unfair for the rest of the brands, instead, all the brands should be incorporated in the survey.
  3. Allowing the participants to see the brand will affect the response, hence, proper care must be taken in avoiding the disclosure of the brand.
  4. Manipulated results are unethical, honest results must be displayed in the commercial.

Step by Step Solution

TABLE OF CONTENTS :
TABLE OF CONTENTS

Part (a) Step 1: Concept Introduction

Unethical behavior is described as actions that violate social norms or are deemed objectionable by the general public. It is an action that goes against what is morally right or proper for a person, a profession, or a business. Individual people, companies, professionals, and officials can all act unethically.

Part (a) Step 2: Explanation

The unethical act here is that the survey is conducted by the supplier of the preferred brand. The seller of a well-known brand will produce skewed results. The solution is for the poll to be conducted by someone who is not affiliated with the brands.

Part (a) Step 3: Final answer

A survey conducted by a seller of a popular brand of apple juice will result in a biased result; alternatively, the poll must be conducted by someone who is unrelated to the seller.

Part (b) Step 1: Concept Introduction

Unethical behavior is described as actions that violate social norms or are deemed objectionable by the general public. It is an action that goes against what is morally right or proper for a person, a profession, or a business. Individual people, companies, professionals, and officials can all act unethically.

Part (b) Step 2: Explanation

It is unethical to not provide all of the available options on the market. As a result, the study's findings will be incorrect. The simplest method to avoid this unethical practice is to combine all of the available juice brands.

Part (b) Step 3: Final answer

Limiting the survey to only two types of brands would be unfair to the other brands; therefore, all brands should be included.

Part (c) Step 1: Concept Introduction

Unethical behavior is described as actions that violate social norms or are deemed objectionable by the general public. It is an action that goes against what is morally right or proper for a person, a profession, or a business. Individual people, companies, professionals, and officials can all act unethically.

Part (c) Step 2: Explanation

If the participants know the name of the juice brand they are tasting, they can utilize their prior taste preferences to determine how it tastes. This will influence the participants' responses, resulting in biased results. This can be prevented by taking extra precautions to ensure that the participants do not discover the name of the juice they would be sampling.

Part (c) Step 3: Final answer

Allowing participants to view the brand will alter their response; therefore, extreme caution is necessary for avoiding brand disclosure.

Part (d) Step 1: Concept Introduction

Unethical behavior is described as actions that violate social norms or are deemed objectionable by the general public. It is an action that goes against what is morally right or proper for a person, a profession, or a business. Individual people, companies, professionals, and officials can all act unethically.

Part (d) Step 2: Explanation

The study's results have been tampered with. It leads customers misguided. One must ensure that their commercial is honest and that the facts and findings of the research study are not manipulated.

Part (d) Step 3: Final answer

Manipulated results are unethical, and honest results must be shown in commercials.

Use the following information to answer the next seven exercises: Studies are often done by pharmaceutical companies to determine the effectiveness of a treatment program. Suppose that a new AIDS antibody drug is currently under study. It is given to patients once the AIDS symptoms have revealed themselves. Of interest is the average (mean) length of time in months patients live once starting the treatment. Two researchers each follow a different set of 40 AIDS patients from the start of treatment until their deaths. The following data (in months) are collected.

Researcher A: 3; 4; 11; 15; 16; 17; 22; 44; 37; 16; 14; 24; 25; 15; 26; 27; 33; 29; 35; 44; 13; 21; 22; 10; 12; 8; 40; 32; 26; 27; 31; 34; 29; 17; 8; 24; 18; 47; 33; 34

Researcher B: 3; 14; 11; 5; 16; 17; 28; 41; 31; 18; 14; 14; 26; 25; 21; 22; 31; 2; 35; 44; 23; 21; 21; 16; 12; 18; 41; 22; 16; 25; 33; 34; 29; 13; 18; 24; 23; 42; 33; 29

List two reasons why the data may differ.

A study was done to determine the age, number of times per week, and the duration (amount of time) of residents using a local park in San Antonio, Texas. The first house in the neighborhood around the park was selected randomly, and then the resident of every eighth house in the neighborhood around the park was interviewed.

“Duration (amount of time)” is what type of data?

a. qualitative(categorical); b. quantitative discrete; c. quantitative continuous

YouPolls is a website that allows anyone to create and respond to polls. One question posted April 15 asks:

“Do you feel happy paying your taxes when members of the Obama administration are allowed to ignore their tax liabilities?”[5]

As of April 25, 11 people responded to this question. Each participant answered “NO!”

Which of the potential problems with samples discussed in this module could explain this connection?

A scholarly article about response rates begins with the following quote:

“Declining contact and cooperation rates in random digit dial (RDD) national telephone surveys raise serious concerns about the validity of estimates drawn from such research.”[6] The Pew Research Center for People and the Press admits: “The percentage of people we interview – out of all we try to interview – has been declining over the past decade or more.”[7]

a. What are some reasons for the decline in response rate over the past decade?

b. Explain why researchers are concerned with the impact of the declining response rate on public opinion polls.

1.18 Table 1.16 contains the total number of fatal motor vehicle traffic crashes in the United States for the period from 1994 to 2011.

Answer the following questions.

a. What is the frequency of deaths measured from 2000 through 2004?

b. What percentage of deaths occurred after 2006?

c. What is the relative frequency of deaths that occurred in 2000 or before?

d. What is the percentage of deaths that occurred in 2011?

e. What is the cumulative relative frequency for 2006? Explain what this number tells you about the data?
