5. A clinical trial is run to assess the efficacy of a new drug to reduce high blood pressure. Patients with a diagnosis of hypertension (high blood pressure) are recruited to participate in the trial and randomized to receive either the new drug or placebo. Participants take the assigned drug for 12 weeks and their blood pressure status is recorded. At the end of the trial, participants are classified as still having hypertension or not. The data are shown below. The Estimated relative risk comparing who are free of hypertension at 12 weeks between groups is: Group Number Randomized Number Free of Hypertension at 12 Weeks Placebo 50 6 New Drug 50 14 A) 0.43B) 1.2C) 4.0D) 2.33

Is there a relationship between autism and what an infant is fed? To determine if there is, a researcher asked a random sample of mothers what they had fed their infant and they also recorded whether or not the child was autistic. Almost all brands of formula sold in the U.S. are now fortified with DHA (docosahexaenoic acid) and ARA (arachidonic acid). The data are in the table below. Do the data provide enough evidence to show that that what an infant is fed and autism are dependent? Test at the 1% level and round expected values to one decimal place. what an infant is fed yes (Observed) yes (Expected Value) no (Observed) no (Expected Value) Row Total breastmilk 6 422 428 formula with DHA/ARA 7 1156 1163 formula without DHA/ARA 15 525 540 Column Total 28 2103 2131 H: HypothesesHo:Ho:Select an answer whether or not a child has autism infant infants yes and Select an answer what an infant is fed infant infants no are Select an answer independent…
A clinical trial was conducted among 178 patients with advanced melanoma (a type of skin cancer). There were two treatment groups. Group A received Interleukin-2. Group B received Interleukin-2 plus a vaccine. Six percent of Group A patients and 17% of group B patients had a complete or partial response to treatment. One issue is that some patients experience side effects and have to discontinue treatment. It was estimated that 21% of patients receiving Interleukin-2 plus a vaccine developed an arrhythmia (irregular heartbeat) and had to discontinue treatment. Since the side effect was attributable to the vaccine, assume that the patients would continue to take Interleukin-2 if arrhythmia developed but not the vaccine and that the probability of a positive response to the treatment would be the same as group A (i.e., 6%)Suppose we have 10 patients who receive Interleukin-2 plus vaccine of whom 2 develop arrhythmia and 8 do not. What is the probability that exactly 2 of the 10 patients…
To demonstrate a causal relationship, the researchers must have appropriate time order and covariation between the variables, and they must have eliminated plausible alternative explanations. What is missing, if anything, in the following cause-and-effect assertions? Explain. A study looks at the promotion time for women and concludes that women face barriers to promotions. Proponents of free college education for all argue that teenage pregnancies and crime would be lower if everyone had the opportunity to go to college. An e-mail circulated stating that a study found that a majority of women who had breast cancer had used deodorant containing a specific chemical and argued that the government should ban that chemical.
To examine adolescent substance abuse, Li, Pentz, and Chou (2002) surveyed 1,807 middle school students from 57 schools. The results showed that a greater risk of adolescent substance abuse was associated with increasing numbers of parents and friends who were sub- stance abusers. However, friends’ use did not affect adolescent substance abuse when parents were nonusers. Is this an example of a survey research design?
A group of 600 patients who suffer from seasonal allergies is asked to participate in a study to determine the effectiveness of a new medication. The patients are divided randomly into two groups, one was given the actual medication and one received a placebo pill. After 2 months of treatment, 64% of the patients who took the medication had fewer allergy symptoms, while only 36% of those who took the placebo had fewer allergy symptoms. a. What is the treatment variable? b. What is the response (or outcome) variable? 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 taking the new medication caused fewer allergy symptoms.
An automotive engineer is investigating two different types of metering devices for an electronic fuel injection system to determine whether they differ in their fuel mileage performance. The system is installed on 10 different cars, and a test is run with each metering device on each car. The data is provided below: Metering Device Car 1 2 1 17.6 16.8 2 19.4 20.0 3 18.2 17.6 4 17.1 16.4 5 15.3 16.0 6 15.9 15.9 7 16.3 16.5 8 18.0 18.4 9 17.3 16.4 10 19.1 20.1 Is there a significant difference between the means of the two metering devices? Use . Interpret the result in the context of the problem. An article in the journal Hazardous Waste and Hazardous Materials (Vol. 6, 1989) reported the results of an analysis of the weight of calcium in standard cement and cement doped with lead. Reduced levels of calcium would indicate that the hydration mechanism in the cement is blocked…
