**Preventing heart attacks:** Medical researchers performed a comparison of two drugs, clopidogrel and ticagrelor, which are designed to reduce the risk of heart attack or stroke in coronary patients. A total of 6745 patients were given clopidogrel, and 6681 were given ticagrelor. Of the clopidogrel patients, 546 suffered a heart attack or stroke within one year, and of the ticagrelor patients, 671 suffered a heart attack or stroke. Can you conclude that the proportion of patients suffering a heart attack or stroke is greater for ticagrelor? Let \( p_1 \) denote the proportion of patients suffering a heart attack or stroke with clopidogrel and \( p_2 \) denote the proportion of patients suffering a heart attack or stroke with ticagrelor. Use the \( \alpha = 0.10 \) level of significance and the critical value method.**Part 1 of 5****State the null and alternate hypotheses.**\[H_0: p_1 = p_2\]\[H_1: p_1 < p_2\]This hypothesis test is a **left-tailed** test.**Part: 1 / 5** [Progress bar indicating Part 1 is complete]**Part 2 of 5****Find the critical value(s).

Blood types: The blood type O negative is called the "universal donor" type, because it is the only blood type that may safely be transfused into any person. Therefore, when someone needs a transfusion in an emergency and their blood type cannot be determined, they are given type O negative blood. For this reason, donors with this blood type are crucial to blood banks. Unfortunately, this blood type is fairly rare; according to the Red Cross, only 7% of U.S. residents have type O negative blood. Assume that a blood bank has recruited 19 donors. Round your answers to four decimal places. Part: 0 / 3 Part 1 of 3 (a) What is the probability that two or more of them have type O negative blood? The probability that two or more of them have type O negative blood is x
In a study reported in the July 2007 issue of the Journal of Epidemiology and Community Health, researchers investigated whether veterans are more likely to commit suicide than nonveterans. They spent 12 years following 104,000 veterans who had served in the armed forces between 1917 and 1994, and compared them with 216,000 nonveterans. They found that 197 veterans and 311 nonveterans committed suicide. Q: How many times more times is a veteran likely to commit suicide than a nonveteran? Round all values to 3 decimal places.

Imagine I wanted to study the effectiveness of the Mediterranean diet on people’s memory. I tested a group of people who strictly followed the Mediterranean diet, another group who followed a typical Western diet, and another whose diet I did not change at all. Before the diet changes began, I gave all my participants a memory test. After six weeks of the diet experiment, I had all participants complete the same memory test again to see how scores would change among the three groups. For this study, identify a parameter and a statistic I might be interested in.
Study 1: A study of 300 high school students was done. Half of them were instructed to drink soda every day. The other half was instructed to not drink soda at all. After one month, the half that were drinking soda had gained an average of five pounds more than the half that did not drink soda. a. Is this a controlled study? Why or why not?
A pharmaceutical company tested the impact of four cholesterol-reducing medications (denoted A, B, C and D) on people at high risk of heart attack. For this clinical trial 20 volunteers with LDL (bad) cholesterol levels of 140 mg/dl were randomly assigned to one of the four medications. The subjects were instructed to take one tablet per day for a period of three months after which their LDL levels were again measured. Below are the amounts (in mg/dl) by which the LDL levels decreased after the three month trial. Medication A Medication B Medication C Medication D 29 31 30 31 30.5 30 32 31.5 30.5 32 31.75 35 31 29.75 27 33 29 31.5 33 29 (d) What assumptions are needed to make this test valid?

A researcher's survey results indicate that about 50% of 12th graders consume less than 300g of vegetables at lunch, about 40% consume 300-600g, and only 10% of them consume more than 600g. A high school conducted a survey of student diets and health information, and reported data about 12th graders' vegetable intake at lunch is reported in the table photo. If researchers wants to find out whether the high school has the same proportions of 12th graders in the vegetable intake categories as reported by the survey, what would the appropiate test statistic be to use and why. Choosing between an ANOVA, Chi -Square independence tests, Chi Square Goodness of Fit, and One sample proportion test?

Hurricane damage: In August and September 2005, Hurricanes Katrina and Rita caused extraordinary flooding in New Orleans, Louisiana. Many homes were severely damaged or destroyed, and of those that survived, many required extensive cleaning. It was thought that cleaning of flood-damaged homes might present a health hazard due to the large amounts of mold present in many of the homes. In a sample of 364 residents of Orleans Parish who had participated in cleaning of one or more homes, 72 had experienced symptoms of wheezing, and in a sample of 184 residents who had not participated in cleaning, 23 reported wheezing symptoms (numbers read from a graph). Can you conclude that the proportion of residents with wheezing symptoms is greater among those who participated in the cleaning of flood-damaged homes? Let p, denote the proportion of residents with wheezing symptoms who had cleaned flood-damaged homes, and let p, be the population proportion with wheezing symptoms who did not…
I collected data on levels of anxiety after receiving three types of therapies (CBT, psycho education, and psycho analysis). Below are the anxiety scores for 9 patients. Is there a difference in anxiety based on treatment type ? CBT: 3, 2, 0 Psycho Education: 8, 8, 9 Psycho Analysis: 10, 12, 12 (Look at the table)
A health scientist is testing the effectiveness of three different diets (Diet A, Diet B, and Diet C). To determine diet effectiveness, a group of 72 participants were weighed and then randomly assigned to adhere to one of the three diets for a month (N = 24 for each group). At the end of the month, each participant was weighed again and the amount of weight lost was calculated in kilograms (kg). Using the variables “Diet” and “Weight Loss kg”, conduct a One-Way, Between Subjects, ANOVA, at α = 0.05, AND conduct Tukey's Post Hoc testing to find out which of the three diets was most effective. Identify the correct symbolic notation for the alternative hypothesis. A. HA: µ1 ≠ µ2 ≠ µ3 B. H0: µ1 = µ2 C. H0: µ1 = µ2 = µ3 D. HA: µ1 ≠ µ2

A researcher is studying the effects of yoga on depression. Participants are randomly assigned to one of two groups: yoga and medication (experimental group); or support group and medication (control group). In this study, the researcher first administers a questionnaire measuring depression to all participants. Then they implement two programs simultaneously: a 6-week yoga program coupled with medication management and a 6-week support group program coupled with medication management. At the end of the 6 weeks, participants complete another questionnaire measuring depression. Finding the change scores from the beginning to end, the researcher then compares the mean change score of the experimental group with the mean change score of the control group. A) What are the independent and dependent variables in this scenario? B) What statistical test would be most appropriate to use in this study? Why? C) Once you have calculated the statistics, how do you know whether the results of the…
