The effectiveness of advertising for two rival products (Brand X and Brand Y) was compared. Market research at a local shopping center was carried out, with the participants being shown adverts for two rival brands of coffee, which they then rated on the overall likelihood of them buying the product (out of 10, with 10 being "definitely going to buy th product"). Brand X Rating 342625 Brand Y 97 5 10 6 8 To test whether they have the same ratings, we use a = 0.05. What is the test statistics Tobs = min{Tobs, obs} and the critical region? (A) Tobs 2, CR = {T<5}. (B) Tobs = 23, CR = {T<7}. (C) Tobs 34, CR = {T≥ 31}. - (D) Tobs =55, CR = {T> 29}.

A study was done comparing the effectiveness of exercise vs medication on loweringblood pressure in patients with high blood pressure. Two hundred subjects wererandomly assigned to two groups. One group was instructed to exercise according tostrict schedule, and the other group was given medication to take. After 3 months,the researchers compared the change in blood pressure between the groups and foundthat the exercise groups experienced a greater drop in blood pressure on average.a. Is this an observational study or an experimental study?b. Explain why a blind study would be difficult to do in this situation.
In a study examining the relationship between coffee consumption and heart disease, the researcher obtained a value of r(120) = -.88, p = .04. The results conclude: Group of answer choices proves that the more coffee you drink, the less chance of heart disease. proves that the less coffee you drink, the greater the chance of heart disease. demonstrates that there is a strong relationship between coffee consumption and heart disease. demonstrates that there is a poor relationship between coffee consumption and heart disease.
A recent study investigated the association between sudden cardiac death and smoking history in women from a large health system. The epidemiologist reviewed the electronic health records of women who died from sudden cardiac death (n=80) and women who died of non-cardiac causes (n=80). The investigator then reviewed these records for smoking history (smoking 1+ pack/day and smoking <1 pack/day) and identified the following results. Sudden Cardiac Death 38 42 Smoke 1+ pack/day Smoke <1 pack/day Calculate the most appropriate measure of association for these data (a)-round to the nearest tenth. Other Causes 10 70
A polling organization is checking its database to see if the data sources it used sampled the same ZIP codes. The variable Datasource=1 if the data source is MetroMedia, 2 if the data source is DataQwest, and 3 if it's Rolling Poll. The organization finds that the correlation between five-digit ZIP code and DATAsource is -0.0229. It concludes that the correlation is low enough to state that there is no dependency between ZIP code and Source of Data. Comment. Choose the correct answer below. OA. The source of the data is categorical, which will almost always result in very low correlation values. These types of correlations can only be interpreted in the rare instances when the correlation is close to - 1 or 1. OB. The source of the data is categorical. The correlation is meaningless. OC. A correlation must be between 0 and 1, so the correlation of -0.0229 must have been calculated incorrectly. OD. A correlation of -0.0229 is very close to zero, which implies that there is a very…
Rangecient of Variaice: 45.31N 6.- The day after Thanksgiving-called Black Friday–is one of the largest shopping days in the United States. A group of researchers conducted interviews with a sample of 38 women shopping on Black Friday to gauge their shopping habits and reported the results in a published paper, in 2011. One question was, "“How many hours do you usually spend shopping on Black Friday?" Data for the 38 shoppers are listed here: 66443 16 4 4 5 6 6 5 5 4 6 5 6 4 5 4 44 7 12 5 86 10 5 8 8 3 38 5 6 10 11.

A data set from a study that examined the effect of a specific diet on blood pressure is provided . Participants (n = 72) were randomly assigned either to a group that was put on the diet (Diet = Present) or to a group that was not put on the diet (Diet = Absent), and researchers wanted to know whether the diet had a significant impact on blood pressure. Fully interpret the results in the context of this study (i.e., report the conclusions as related to the research question).
Nota, Ferrari, Soresi, and Wehmeyer (2007) measured the relationship between IQ and the four measures of self-determination in a sample of n = 141 participants. They reported a negative correlation between IQ and self-determination in daily activities, r = -0.42, p < .01, and a negative correlation between IQ and self-determination in expressing emotions and options, r = -0.16, p > .05. a. Which correlation is significant? b. Which is the stronger correlation?
A researcher hypothesizes that the lowering in cholesterol associated with weight loss is really due to exercise. To test this, the researcher carefully controls for exercise while comparing the cholesterol levels of a group of subjects who lose weight by dieting with a control group that does not diet. The difference between groups in cholesterol is not significant. Can the researcher claim that weight loss has no effect?

Solid fats are more likely to raise blood cholesterol levels than liquid fats. Suppose a nutritionist analyzed the percentage of saturated fat for a sample of 6 brands of stick margarine (solid fat) and for a sample of 6 brands of liquid margarine and obtained the following results: Stick = [25.4,25.3,25.7,25.6,26.7,25.8] Liquid= [16.9,16.7,17.5,17.2,17.3,16.6] We want to determine if there a significant difference in the average amount of saturated fat in solid and liquid fats.

Legumes have various health benefits, including their high fiber content, which may lower the risk of colon cancer. An experiment was conducted to evaluate the effect of garbanzo beans on the presence of Aberrant Crypt Foci (ACF) in rats. The number of ACF is an indicator of the prevalence of colon cancer. In treatment A, rats were fed 5% garbanzo beans, while Control rats (treatment B) didn't receive garbanzo be an in their diet. The data below represent the number of ACF in rats after 8 weeks of feeding.
