STATE: Cardiovascular disease is a major cause of death and illness worldwide, with high blood pressure and high LDL
cholesterol both being established risk factors. Because most cardiovascular events occur in persons with average risk
factors. Because most cardiovascular events occur in persons with average risk and no previous cardiovascular disease
history, the present research examined the simultaneous use of both blood pressure reducing drugs and cholesterol
reducing drugs on this population, rather than focusing on only those on only those at high risk. Subjects included men at
least 55 years old and women at least 65 years old without cardiovascular disease who had at least one additional risk
factor besides age, such as recent or current smoking, hypertension, or family history of premature coronary heart
disease. Those with current cardiovascular disease were excluded from the study. Subjects were randomly assigned to the
treatment (cholesterol and blood pressure reducing…
“The US Centers for Disease Control and Prevention said about 72 million Americans—nearly one out of every four of the country’s 304 million residents—are considered obese. Millions more are designated as overweight.” The American trend toward obesity has prompted many physicians to offer weight-loss programs to their patients. [Source: Price, W. T. “Physicians Get into the Weight-Loss Business.” Florida Today, July 7, 2008.]
A physician conducted an experimental study to compare the effectiveness of four different weight-loss programs. In the study, 64 obese adults were randomly assigned to the four programs so that each program had 16 adults. The programs lasted for six months. The weights of the subjects were measured before and after the programs, and each subject’s weight loss was computed in pounds.
The following table summarizes the results of the study, giving the number of observations and the sample mean and variance of the subjects’ weight loss in each program.…

- College administrations are continually perplexed about how to deal with hazing issues on their campuses. But how widespread is hazing, and, in fact, what constitutes hazing anyway? One study tried to get an objective handle on this persistent college phenomenon by carrying out a large survey of college and university students on 53 campuses. The study leaders defined hazing as "any activity expected of someone joining or participating in a group that humiliates, degrades, abuses, or endangers them regardless of a person's willingness to participate." The two types of activities receiving the highest rate of participation overall were "participate in a drinking game" and "sing or chant by yourself or with a few selected team members in a public situation that is not related to the event, game, or practice." The table below shows the sample sizes for those responding and the proportions for each activity across a variety of typical campus groups. In comparing these groups, regard the…arrow_forwardThe report Controlling Road Rage: A Literature Review and Pilot Study was prepared for the AAA Foundation for Traffic Safety by D. Rathbone and J. Huckabee. The authors discussed the results of a literature review and pilot study on how to prevent aggressive driving and road rage. Road rage is defined as “… an incident in which an angry or impatient motorist or passenger intentionally injures or kills another motorist, passenger, or pedestrian, or attempts or threatens to injure or kill another motorist, passenger, or pedestrian.” One aspect of the study was to investigate road rage as a function of the day of the week. The following table provides a frequency distribution for the days on which 69 road-rage incidents occurred.

- Attitudes toward interracial relationships have changed dramatically since the Supreme Court ruled bans on interracial marriage were unconstitutional in Loving v. Virginia in 1967. A researcher interested in learning about current attitudes recruited a diverse sample of undergraduate students throughout the United States were asked to classify themselves as: (1) Asian, (2) Black or African American, (3) American Indian or Alaska Native, (4) White, (5) Native Hawaiian or Other Pacific Islanders, or (6) Other (e.g., some other race, two or more races). Each person was also asked whether their family would consider it acceptable (yes or no) is they married someone from a different racial category. What statistical test should be used to see if acceptability differs between people from different racial categories? A. Is this a relationship test or a difference test? Explain your rationale. B. What would be the appropriate statistical test? Explain your rationale.arrow_forwardA researcher is interested in learning whether young people whose fathers are absent from home are more likely to engage in delinquent behaviours. She compares the arrest rates of boys whose fathers are absent with those of boys whose fathers are present at home across socio economic status (e.g., lower SES, middle SES, upper SES). What type of data is the researcher collecting? Select one: A. archived data B. self-report data C. case study data D. experimental data E. naturalistic observationarrow_forwardThe Terri Schiavo Case. In the early part of 2005, the Terri Schiavo case received national attention as her husband sought to have life support removed, and her parents sought to maintain that life support. The courts allowed the life support to be removed, and her death ensued. A Harris Poll of 1010 U.S. adults was taken by telephone on April 21, 2005, to determine how common it is for life support systems to be removed. Those questioned in the sample were asked: (1) Has one of your parents, a close friend, or a family member died in the last 10 years? (2) Before (this death/these deaths) happened, was this person/were any of these people, kept alive by any support system? (3) Did this person die while on a life support system, or had it been withdrawn? Respondents were also asked questions about age, sex, race, education, region, and household income to ensure that results represented a cross section of U.S. adults. a. What kind of sampling design was used in this survey? Explain…arrow_forward
- Childhood vaccinations: In January 2015, the Pew Research Center reported results from one of their surveys. “Asked about whether vaccines for childhood diseases such as measles, mumps, rubella (MMR) and polio should be required or left up to parental choice, 68% of adults say such vaccines should be required while 30% say that parents should be able to decide whether or not to vaccinate their children.” The following is an excerpt from the press release: The survey of the general public was conducted using a probability-based sample of the adult population by landline and cellular telephone Aug. 15-25, 2014, with a representative sample of 2,002 adults nationwide. The margin of sampling error for results based on all adults is plus or minus 3.1 percentage points. Source: C. Funk and L. Raine.

A U.S. News & World Report article about polls stated: "On sensitive issues, people tend to give 'acceptable' rather than honest responses; their answers may depend on the gender or race of the interviewer." To support that claim, data were provided for an Eagleton Institute poll in which surveyed men were asked if they agreed with this statement: "Abortion is a private matter that should be left to the woman to decide without government intervention." We will analyze the effect of gender on male survey subjects only. Table is based on the responses of surveyed men. Gender of Interviewers Women 308 92 Men 560 Men who agree Men who disagree 240 Assume that the survey was designed so that male interviewers were instructed to obtain 800 responses from male subjects, and female interviewers were instructed to obtain 400 responses from male subjects.

A subsample of the HRS participated in an Internet-based survey that collected information on a number of topical areas, including health (physical and mental health behaviors), psychosocial items, economics (income, assets, expectations, and consumption), and retirement. Two of the questions asked were: "Would you say your health is excellent, very good, good, fair, or poor?" and “Do you smoke cigarettes now?" Here is the two-way table that summarizes the answers on these two questions: Current smoker Нealth Yes No Excellent 25 484 Very good 115 1557 Good 145 1309 Fair 90 545 Рoor 29 11 This table gives the responses of a survey of 4310 Americans to questions about their health and whether they currently smoke cigarettes.
