Chapter 1: Q3-21BSC (page 1)

In Exercises 21鈥�28, determine whether the study is an experiment or an observational study, and then identify a major problem with the study.

Online News In a survey conducted by USA Today, 1465 Internet users chose to respond to this question posted on the USA Today electronic edition: 鈥淚s news online as satisfying as print and TV news?鈥� 52% of the respondents said 鈥測es.鈥�

Short Answer

Expert verified

The response of 1465 internet users to a survey question is considered an observational study.

An underlying problem with the study is that the given population generates a biased response for the particular question of the survey. Therefore, the claim that a majority of the population is happier with online news as compared to print and TV news is inaccurate.

Step by step solution

01

Given information

In a survey, 52% of the 1465 respondents said 鈥淵es鈥� to a survey question.

02

Observational study and experimental study

Anobservational study revolves around observing a group of units without deliberately altering their behavior.

Anexperimental study revolves around testing an observation made about a group of units by initiating a deliberate change.

03

Identification of the type of study

The given study deals with only recording responses of a group of 1465 internet users without applying any modification to them. Thus, it is an observational study.

04

Identification of the major problem

Since the respondents are readers of only the electronic edition of the American daily USA Today, they neither have any recent exposure to the printed edition nor the TV news.

The population of respondents is biased, and thus to state that 52% of the respondents said 鈥測es鈥� to the fact that online mode of news is more satisfying than print and TV news is not accurate.

Statistical Significance and Practical Significance. In Exercises 13鈥�16, determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

MCAT The Medical College Admissions Test (MCAT) is commonly used as part of the decision-making process for determining which students to accept into medical schools. To test the effectiveness of the Siena MCAT preparation course, 16 students take the MCAT test, then they complete the preparatory course, and then they retake the MCAT test, with the result that the average (mean) score for this group rises from 25 to 30. There is a 0.3% chance of getting those results by chance. Does the course appear to be effective?

In Exercises 17鈥�20, refer to the sample of body temperatures (degrees Fahrenheit) in the table below. (The body temperatures are from a data set in Appendix B.)

Context of the Data: Refer to the table of body temperatures. Is there some meaningful way in which each body temperature recorded at 8 AM is matched with the 12 AM temperature?

Exercises 5鈥�8 refer to the study of an association between which ear is used for cell phone calls and whether the subject is left-handed or right-handed. The study is reported in 鈥淗emispheric Dominance and Cell Phone Use,鈥� by Seidman et al., JAMA Otolaryngology鈥� Head & Neck Surgery, Vol. 139, No. 5. The study began with a survey e-mailed to 5000 people belonging to an otology online group, and 717 surveys were returned. (Otology relates to the ear and hearing.)

Response Rate What percentage of the 5000 surveys were returned? Does that response rate appear to be low? In general, what is a problem with a very low response rate?

Discrete/ Continuous Data Which of the following describe discrete data?

a. The numbers of people surveyed in each of the next several years for the National Health and Nutrition Examination Surveys.

b. The exact foot lengths (measured in cm) of a random sample of statistics students.

c. The exact times that randomly selected drivers spend texting while driving during the past 7 days.

Determine whether the data are from discrete data or continuous data set.

The Insurance Institute for Highway Safety collects data consisting of the numbers of motor vehicle fatalities caused by driving while texting.
