Calcium and Blood Pressure Does increasing the amount of calcium in our diet reduce bloodpressure? Examination of a large sample of people revealed a relationship between calcium intakeand blood pressure. Such observational studies do not establish causation. Researchers thereforedesigned a randomized comparative experiment.The subjects were 21 healthy men who volunteered to take part in the experiment. They wererandomly assigned to two groups: 10 of the men received a calcium supplement for 12 weeks,while the control group of 11 men received a placebo pill that looked identical. The experimentwas double-blind. The response variable is the decrease in systolic (top number) blood pressurefor a subject after 12 weeks, in millimeters of mercury. An increase appears as a negative number.Do the data provide convincing evidence that a calcium supplement reduces blood pressure morethan a placebo, on average, for subjects like the ones in this study?Group 1 (calcium)Group (placebo)7-1-4 18 17 -312 -1 -3 3 -5 5-5 1 10 11 -22 -11 -1 -3

Researchers investigate how the presence of cell phones influence the quality of human interaction. Subjects are randomly selected from a population and divided into an experimental group that is asked to leave their phones in the front of the room and a control group that are not asked to leave their cell phones at the front of the room. Subjects are left alone for 10 minutes and then asked to take a survey designed to measure quality of interactions they had with others in the experiment. What statistical test is appropriate?
Dr. Ngo would like to know whether there is a relationship between the number of minutes per day that a person spends in prayer or quiet meditation and the degree of conflict that they have in their interpersonal relationships. He asks participants to complete an assessment of interpersonal conflict, with scores ranging from 1 (very low interpersonal conflict) to 50 (very high interpersonal conflict). He collects data from a random sample of 10 participants. The data is as follows: Participant Minutes in Prayer/Meditation Conflict in Relationships 1 3 25 2 30 14 3 0 29 4 23 21 5 5 32 6 16 6 7 0 43 8 18 12 9 7 37 10 27 19 Using SPSS, conduct the appropriate analysis.

Acne is a common skin disease that affects most adolescents and can continue into adulthood. A study compared the effectiveness of three acne treatments and a placebo, all in gel form, applied twice daily for 12 weeks. The study's 517 teenage volunteers were randomly assigned to one of the four treatments. Success was assessed as clear or almost clear skin at the end of the 12 week period. The results of the study can be seen in the table below. Using the appropriate statistical test, determine if there is significant evidence that the four treatments perform differently. If so, how do they compare.

A researcher conducts an independent-measures study examining how the brain chemical serotonin is related to aggression. One sample of rats serves as a control group and receives a placebo that does not affect normal levels of serotonin. A second sample of rats receives a drug that lowers brain levels of serotonin. Then the researcher tests the animals by recording the number of aggressive responses each of the rats display. The data are as follows. Control Low Serotonin n = 10 n = 15 M = 14 M = 19 SS = 180.5 SS = 130.0 A. Does the drug have a significant effect on aggression?Use an alpha level of .05, two tails.

Female college student participation in athletics has increased dramatically over the past few decades. Sports medicine providers are aware of some unique health concerns of athletic women, including disordered eating. A study compared disordered-eating symptoms and their causes for collegiate female athletes (in lean and non lean sports) and nonathletes. The sample mean of the body dissatisfaction assessment score was 13.4 (s=7.9) for 15 lean sports athletes (those sports that place value on leanness, including distance running, swimming, and gymnastics) and 7.4 (s=5.8) for the 67 non-lean athletes. Assume equal population standard deviations. Find the standard error for comparing the means. Construct a 95% confidence interval for the difference between the mean body dissatisfaction for lean sport athletes and non lean sport athletes. Interpret.
Consider an experiment to determine the effects of alcohol and marijuana on driving. Five randomly selected subjects are given alcohol to produce legal drunkenness and then are given a simulated driving test (scored from a top score of 10 to a bottom score of 0). Five different randomly selected subjects are given marijuana and then the same driving test. Finally, a control group of five subjects is tested for driving while sober. The driving test scores and the One-Way ANOVA table for these data are shown below. Test the hypothesis that there is a difference among the means of the three groups at 1% significance level.

Q1: Placebo effect of exercise In a high-profile research study, Crum and Langer (2007) performed an experiment to test whether the relationship between physical exercise and health is impacted by one's mindset: in other words, if there is any "placebo effect" of exercise. A sample of 84 randomly selected hotel workers in the United States were placed either into a treatment group (n=44) or control group (n=40) depending on which hotel they worked at. The treatment group was given information demonstrating how their work is good physical exercise, while the control group was not given this information. They measured the body mass index (BMI) for each worker before the experiment and again four weeks after the experiment. a. Are the treatment group and control group independent of each other, and if so why? b. Now consider the treatment group alone: are the measurements of BMI taken before and after the experiment independent of each other, and if so why? c. What is the most appropriate…
A scientist is studying the effect of a new type of exercise program on cardiovascular health. The scientist randomly assigns individuals to either the exercise program or a control group. The scientist wants to determine if the exercise program has a statistically significant effect on cardiovascular health. The scientist monitors cardiovascular health by measuring the blood pressure of each individual.
