A research group is interested in the relationship between the consumption of fatty foods and cholesterol levels in American men between the ages of 25 and 50. The
researchers randomly selected 749 medical records of men who suffer from high cholesterol. The researchers recorded if the participant did not eat fatty foods, ate a
moderate amount of fatty foods, or ate an excessive amount of fatty foods. They found that men who had high cholesterol tended to eat an excessive amount of fatty
foods.
a. Identify the population for the study.
b. Identify the sample for the study.
c. Was this an observational study or a controlled experiment? Explain how you know.
d. Assuming the rest of the study was well-designed, use your answers to discuss whether it would be reasonable to conclude that eating fatty foods caused high cholesterol.
Researchers recruited 1000 10- and 20-year-olds
to participate in a study about age differences in
aggression and the impact of violent video games
on aggression. For 1-hour per day, half the
participants were randomly assigned to play
violent video games, while the other half played a
nonviolent video game. A test for aggression was
administered at the end of the year, and each
participant received a score between 1 and 50
(higher scores indicate greater aggression). The
results of the study are shown below:
Factor 1

Is there a main effect of age? If so, which age shows
more aggression?
This exercise uses data from a study designed to examine the effect of doing synchronized movements (such as marching in step or doing synchronized dance steps) and the effect of exertion on many different variables, such as pain tolerance and attitudes towards others. In the study, 264 high school students in Brazil were randomly assigned to one of four groups reflecting whether or not movements were synchronized (Synch = yes or no) and level of activity (Exertion = high or low).1 Participants rated how close they felt to others in their group both before (CloseBefore) and after (CloseAfter) the activity, using a 7-point scale (least close to most close). Participants also had their pain tolerance measured using pressure from a blood pressure cuff, by indicating when the pressure became too uncomfortable (up to a maximum pressure of 300 mmHg). Higher numbers for this PainTolerance measure indicate higher pain tolerance. The full dataset is available in SynchronizedMovement.What…

- To study the effectiveness of possible treatments for insomnia, a sleep researcher conducted a study in which four participants were instructed to count sheep (the Sheep Condition), four were told to concentrate on their breathing (the Breathing Condition), and four were not given any special instructions (the Control Condition). The average number of minutes taken for participants to fall asleep over the next seven days were 39, 33, 42, and 38 minutes for the Sheep condition; 33, 25, 31, and 27 minutes for the Breathing condition; and 44, 41, 38, and 41 for the Control condition. The researcher obtained this omnibus one-way ANOVA result: F (2, 9) = 14.04, p < .01 where Sheep: M = 38, S2 = 14; Breathing: M = 29, S2 = 13.33; Control: M = 41, S2 = 6, Explain what that result means in relation to the researcher’s original question. Further, the researcher conducted a planned contrast between the means for those in the Sheep Condition versus those in the Breathing Condition and found F…arrow_forwardThe Joint Commission on Accreditation of Healthcare Organizations mandated that hospitals ban smoking by 1994. To study the effects of this ban on smoking behaviors, subjects were randomly selected from two different populations: those from hospitals with the ban and those from hospitals without the ban. Investigators were interested in determining if this smoking ban had any impact on the proportion of smokers employed at each hospital that then quit smoking. Let px be the proportion of smokers from hospitals that implemented the ban who quit smoking during the study period. Let py be the proportions of smokers from hospitals without the ban who quit smoking during the study period. Please select the appropriate hypotheses. H0: px = 0.50 HA: px ≠ 0.50 H0: px-py ≥ 0 HA: px-py H0: px-py ≤ 0 HA: px-py > 0 H0: px-py = 0 HA: px-py ≠ 0arrow_forwardKava is a beverage or extract that is made from Piper methysticum, a plant native to the western Pacific islands. Suppose that, in a randomized comparative experiment to determine if taking kava daily can reduce insomnia, a group of participants with insomnia were randomly assigned to take kava (treatment group) or a placebo (control group). After six weeks, the participants were interviewed to see if they experienced a decrease in insomnia. The table shows the results from the sample. The counts are the number of people in each group who experienced a decrease in insomnia.

- Elissa Epel, a professor of health psychology at the University of California–San Francisco, studied women in high- and low-stress situations. She found that women with higher cortisol responses to stress ate significantly more sweet food and consumed more calories on the stress day compared with those with low cortisol responses, and compared with themselves on lower stress days. Increases in negative mood in response to the stressors were also significantly related to greater food consumption. These results suggest that psychophysiological responses to stress may influence subsequent eating behavior. Over time, these alterations could impact both weight and health. You are interested in studying whether students living in the dorms or students living off campus have higher cortisol levels. You ask a sample of n₁ = 25 students living in the dorms and n₂ = 30 students living off campus to record their afternoon cortisol levels for a week. The average cortisol level for students living…arrow_forwardResearchers have noted a decline in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggest that the antioxidants in foods such as blueberries may reduce and even reverse these age-related declines (Joseph et al., 1999). To examine this phenomenon, suppose that a researcher obtains a sample of n = 16 adults who are between the ages of 65 and 75. The researcher uses a standardized test to measure cognitive performance for each individual. The participants then begin a 2-month program in which they receive daily doses of a blueberry supplement. At the end of the 2-month period, the researcher again measures cognitive performance for each participant. The results show an average increase in performance of MD = 7.4 with SS = 1215. Does this result support the conclusion that the antioxidant supplement has a significant effect on cognitive performance? Use a two-tailed test with α = .05.

- The drug X is marketed to help protect against male pattern baldness, and it also may protect against prostate cancer. A large sampleof healthy men over age 60 were randomly assigned to receive either a daily drug X pill or a placebo. The study lasted nine years and the men had annual check-ups and a biopsy at the end of the study. Prostate cancer was found in 815 of 4368 men taking drug X and in 1176 of the 4698 men taking a placebo.
