Transcribed Image Text:Problem1: Exercise and diet are being studied as possible substitutes
for medication to lower blood pressure. Three groups of subjects will
be used to study the effect of exercise. Group 1 is sedentary, while
group 2 walks and group 3 swims for 1 hour a day. Half of each of the
three exercise groups will be on a salt-free diet. An additional group
of subjects will not exercise or restrict their salt, but will take
the standard medication.

- A researcher conducts a survey examining eating and sleeping behavior as well as academic performance for a group of elementary school children. The results of the survey indicate that the children who eat a more nutritious breakfast tend to have better grades than the children who have a breakfast low in nutrition. However, the research suspects that the children's parents may be responsible for this relationship. Specifically, the better-educated parents probably encourage their children to eat better food and work harder in school compared to parents with less education. If the researcher is correct, this is an example of the_ O A. criterion problem O B. directionality problem O C.third-variable problem D. reversal problem Reset Selection 7,821 MAR etv A A O w 4 F7 F8 F9 F10 F11 F12 F2 & 3 4 5 7 9. %3D E Yarrow_forward0 to ld 16.

This is because nausea is common for people who have the flu. From past studies you know that about 34% of people who get the flu experience nausea. You collected data on 1926 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 711 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than 34%. a) Identify the null and alternative hypotheses?

- A drug treatment can sometimes be affected by the use of another drug taken concomitantly. This is why doctors and pharmacists routinely ask patients about all the drugs they use, even the ones available over the counter. One study examined the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) on the efficacy of the antidepressant citalopram in clinically depressed individuals. Data from a large clinical trial were reviewed, and clinical remission from depressive symptoms was assessed for individuals who had taken NSAIDs concomitantly and those who had not. The findings are given in the table. NSAID use No NSAID use Remission 182 628 No remission 227 509 How strong is the evidence that concomitant NSAID use lowers the effectiveness of the antidepressant citalopram?

The nurse practitioner in charge of the clinic tells you that asthma affects around 11% of the Australian population, and results in around 40,000 hospital admissions each year. She also tells you that the common pharmacological treatments can have long-term side effects, so she is keen to promote holistic methods to assist patients in controlling their asthma. You are interested to know whether diet can have an effect on asthma, and decide to find out. Construct a searchable clinical question using the PICO formula, identifying the PICO elements clearly.arrow_forwardBeryllium is an extremely lightweight metal that is used in many industries, such as aerospace and electronics. Long-term exposure to beryllium can cause people to become sensitized. Once an individual is sensitized, continued exposure can result in chronic beryllium disease, which involves scarring of the lungs. In a study of the effects of exposure to beryllium, workers were categorized by their duration of exposure (in years) and by their disease status (diseased, sensitized, or normal). The results were as follows: Duration of Exposure <1 1 to <5 ≥5 Diseased 14 13 18 Sensitized 11 20 15 Normal 78 140 209 Test the hypothesis of independence. Use the a=0.10 level of significance and the P-value method with the TI-84 Plus calculator. What do you conclude? State the null and alternate hypotheses.arrow_forward

This is because nausea is common for people who have the flu. From past studies you know that about 30% of people who get the flu experience nausea.

Does When Food Is Eaten Affect Weight Gain?A study was introduced that examined the effect of light at night on weight gain in mice. In the full study of 27 mice over a four-week period, the mice who had a light on at night gained significantly more weight than the mice with darkness at night, despite eating the same number of calories and exercising the same amount. Researchers noticed that the mice with light at night ate a greater percentage of their calories during the day (when mice are supposed to be sleeping). The computer output shown below allows us to examine the relationship between percent of calories eaten during the day, DayPct, and body mass gain in grams, BMGain. A scatterplot with regression line is also shown below (attached image).Pearson correlation of BMGain and DayPct =0.740P-Value =0.000--------------------------------------------------------------The regression equation isBMGain=1.11+0.127DayPct Predictor Coef SE Coef T P Constant 1.113 1.382…arrow_forwardA researcher is interested in the effects of cocaine on learning. A group of rats is randomly assigned to receive either cocaine or a non-harmful saline solution. The rats are taught how to run a maze. The cocaine rats need to be reared away from the control group rats, so they are handled and taught by one experimenter, and the control group rats are handled and taught by another experimenter. The results showed that the control group rats learned how to run the maze more quickly than the cocaine rats. 1. What is the independent variable? 2. What is the dependent variable? 3. What is the confounding? 4. How could the confounding be fixed?arrow_forward
