A study is run to evaluate the effectiveness of an exercise program in reducing systolic Ate blood pressure in patients with pre-hypertension. A total of 15 patients with pre- 12 hypertension enrolled in the study, and their systolic blood pressures are measured. Each patient then participated in an exercise training program where they learned proper techniques and execution of a series of exercises. Patients were instructed to do the exercise program three times per week for six weeks. After six weeks, systolic blood pressures were again measured, and data were recorded. This study sought to determine if there is a difference in systolic blood pressures after participating in the exercise program as compared to before. What is the most appropriate statistical test to be used to answer the research objectives? a. Spearman Correlation Coefficient b. Pearson Correlation Coefficient c. Wilcoxon Signed Ranks Test d. Mann-Whitney U Test
Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Patients experiencing symptoms of a heart attack are routinely transported to a hospital in an ambulance. In a study of a new treatment thought to reduce damage to the heart, patients experiencing symptoms of a heart attack were randomly assigned to one of two groups. During transportation to the hospital, patients in one group received standard care, and patients in the other group received the new treatment consisting of standard care and the application of a blood pressure cuff. The response variable measured for each patient was a number between 0 and 1, referred to as the myocardial salvage index (MSI). A higher MSI value indicates a more positive outcome for the patient. Summary statistics for the MSI responses of the two groups are shown in the table below. Do the data provide…
A textbook company is conducting research to evaluate the effectiveness of their new curriculum for AP Statistics. They select a random sample of 1008 students who used a traditional curriculum and find that 634 of these students passed the AP exam. In a random sample of 825 students who used the new curriculum, 561 students passed the AP exam. A. The textbook company’s statisticians would like to increase the power of their test. Describe two ways they could do so.

Lecture(12.13): Researchers were investigating anxiety in first year college students.According to the anxiety and depression association of America 18% of adults in the U S aged 18 years or older suffer from anxiety disorders making it the most common mental illness.800 first year students from three selected programs completed the questionarre The researchers were interested in whether more people who suffered from anxiety engaged in a specific avtivity aka whether the activity was related to anxiety. Therefore the data was divided based on those who were suffering with activity and those who were not of activity. Here is your questionarre What is your program of study? (a) Psychology (b) Engineering (c) Business Do you feel more anxious when thinking about completing assignments or exams.? (a) Assignments (b) Exams Over the school term have you experienced any of the following problems? Feeling nervous/anxious on the edge. (a) Yes (b) No. Not being able to stop or control…
Data are collected in a clinical trial evaluates a new compound designed to improve wound healing in traumu patients. The new compound is compared against a placebo. After treatment for 5 days with the new compound or placebo , the extent of wound healing is measured and the data are shown table 7-51 Is there a difference in the extent of the wound healing by treatment? Run the appropriate test at a 5% significance.(Hint: Are treatment and the precent of wound healing independent?)
Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 44 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.30 ml/kg for the distribution of blood plasma.
The quality department at ElectroTech is examining which of two microscope brands (Brand A or Brand B) to purchase. They have hired someone to inspect six circuit boards using both microscopes. Below result in terms of a number of defects (e.g., solder voids, misaligned components) found using each microscope. (Note that the data for two brands can be paired) State all the assumptions required to define the test statistic. State the test Statistic in notations first and then calculate its value Find the p-value Carry out test of hypotheses at 1% level of significance and state the conclusion in context of problem. Calculate 99% confidence interval for the true average difference in defects found for two microscope brands.

A researcher is interested in studying the effects of altitude on cognitive performance (e.g., perception, memory, problem solving, etc.). The researcher finds a group of experienced mountain climbers (n = 10) who volunteer to participate in the study. All of the climbers are tested at three different altitudes—at sea level (in the researchers’ laboratory at the University of California, San Diego), at the base camp (9,000 feet above sea level), and at 23,000 feet above sea level (at the peak of Mt. Denali in Alaska). At each location, the climbers perform a memory task (remember a list of 16 non-words like “biv”), and the accuracy of their memory is recorded (i.e., # of correctly recalled words). a. pls name the independent variable, dependent variable, levels of the IV, and the type of experiment design of this study (i.e., b/w- or w/i-subject design ) b. on what level of measurement is accuracy of memory assessed? (i.e., is it on nominal, ordinal, interval, or ratio?
