a pharmaceutical company is testing a new drug for reducing cholesterol levels. to approve the drug for the next round of testing, they need to show that this drug reduces mean total cholesterol level by at least 50 mg/dl. They initially plan a study that involves 50 subjects and a significance level of a=0.05, but they discover that the power of the test against this effect size is only 0.24. What are two ways they can increase the power of the test without changing effect size?

The placebo effect is particularly strong in patients with Parkinson's disease. To understand the workings of the placebo effect, scientists measure activity at a key point in the brain when patients receive a placebo that they think is an active drug and also when no treatment is given. The same six patients are measured both with and without the placebo, at different times.The six differences (treatment minus control) had x = −0.331 and s = 0.172. Is there significant evidence of a difference between treatment and control? (Round your answer to two decimal places. Assume a 95% confidence level.)
In an observational study, it was noticed that people that eat more chocolate tend to have better blood flow than the general population. Researchers wonder whether the improved blood flow might be caused by flavanols (a molecule found in many foods). Dark chocolate contains a high concentration of flavanols, but milk chocolate contains a much lower concentration. How could the researchers design an experiment to determine the effects of flavanol on blood flow from the different types of chocolate?
A diabetic person is interested in determining how the amount of aerobic exercise impacts his blood sugar. When blood sugar reaches 170 mg/dl, he goes out for a run at a pace of 10 minutes per mile. On different days, he runs different distances and measures his blood sugar after completing his run. The preferred blood sugar level is in the range of 80 to120 mg/dl. Levels that are too low or too high are extremely dangerous. The data generated are given in the following table: Distance (miles),x Blood sugar(mg/dl gram),y 2 136 2 146 2.5 131 2.5 125 3 120 3 116 3.5 104 3.5 95 4 85 4 94 4.5 83 4.5 75 Based on the scenario above, analyse the data with appropriate statistical methods and describe your findings in details. Use alpha=0.05 [note: use hypothesis, test statistics confidence interval etc.] ]
Karrie studied the effects of coffee drinking and subsequent development of pancreatic cancer. She got the following results: Risk Ratio (RR) = 0.35 p-value = 0.065 What does RR of 0.35 tells you? A. There is higher risk for pancreatic cancer among coffee drinkers B. RR is not enough to estimate whether there is risk or not C. Coffee consumption is associated with pancreatic cancer D. There is lesser risk for pancreatic cancer among coffee drinkers
A medical student at a community college in city Q wants to study the factors affecting the systolic blood pressure of a person (Y). Generally, the systolic blood pressure depends on the BMI of a person (B) and the age of the person A. She wants to test whether or not the BMI has a significant effect on the systolic blood pressure, keeping the age of the person constant. For her study, she collects a random sample of 150 patients from the city and estimates the following regression function: Y= 15.50 +0.90B + 1.10A. (0.48) (0.35) The test statistic of the study the student wants to conduct (Ho: B, =0 vs. H4: B, #0), keeping other variables constant is. (Round your answer to two decimal places.) At the 5% significance level, the student will v the null hypothesis. Keeping BMI constant, she now wants test whether the age of a person (A) has no significant effect or a positive effect on the person's systolic blood pressure. So, the test statistic associated with the one-sided test the…

Two types of medical devices used for knee replacement are being studied to see if the type of knee replacement used affects the rate of infection for a specific bacterial infection. The infection rate for a specific bacterial infection after surgery for device A is 0.0043. The rate for the same bacterial infection is 0.0121 for device B. How does the risk of developing the bacterial infection in individuals using device B compare to the risk of developing the bacterial infection in individuals using device A? Individuals using device A are 2.814 times more likely to develop the bacterial infection of interest than individuals using device B. Individuals using device B are 2.814 times more likely to develop the bacterial infection of interest than individuals using device A. Individuals using device A are 1.35 times more likely to develop the bacterial infection of interest than individuals using device B. Individual using device B are 1.35 times…

Please also explain why you determined whether or not the results are statistically significant. A student finds a correlation of r = .04 between the number of units the students in his research methods class are taking and the students’ level of stress.
Your daughter is wasting my husband's money by trying to collect 6 rare photocards from a foreign album. Calculate the average number of albums she needs to buy in order to get all the 6 collectibles. Use the three trials shown below for your simulation.(Note: Treat the data vertically, and in order).
You are a researcher who wants to know what the mean (µ) level of anxiety would be for the whole population if they were all receiving a new anti-anxiety therapy. You can’t give the therapy to the whole population, so you give it to a sample, and you get M = 32.1 as the average anxiety level for the sample on the therapy. What is the reason that you can’t just simply assume that µ = 32.1? You didn’t use random assignment Sampling error Descriptive statistics Inferential statistics
A new cream was developed to reduce the irritation caused by poison ivy. To test the effectiveness, researchers placed an ad online asking for volunteers to participate in the study. One hundred subjects replied and were informed that one group would receive the new cream and the other group would Which of the following accurately describes the benefit of comparison in the experiment? O The overall level of irritation can be compared to see if the new cream had a significant effect. O The level of irritation for both groups can be receive a cream with no active ingredient. All 100 subjects were exposed to poison ivy. Fifty were then randomly assigned to the group with the new cream, and 50 were randomly assigned to the group with the cream with no active ingredient. After three days, the subjects' level of irritation was measured. compared to see if the new cream had a significant effect. O The level of irritation in the treatment group only can be compared to see if the new cream had…
