The goal of the study is to determine if the medications differ. Twenty men age 50-60 years old are selected for the study. Ten men are chosen at random to receive the first medication and the other 10 men receive the second medication. Each of the 20 men is monitored for one month to determine the change in blood pressure over that time. Minitab provides the 95% confidence interval for (mu1 - mu2) (2.63, 14.18) a. Interpret this 95% CI. b. What assumptions (be specific) are necessary to construct this CI?
- The number of Muslims continues to grow throughout the world, and they are currently thesecond-largest religious group in the world. Knowing that this group has been the target of falsebeliefs about their religion, a researcher is interested in whether people who have moreinteractions with Muslim people are less likely to believe negative statements about Islam. To dothis, they surveyed a large sample of participants across Western Europe and asked themquestions about how frequently they interact with Muslim people as well as how much theyagreed with negative statements about Islam. What statistical test should be used to determine ifthere if how frequently survey participants interact with Muslim people predicts how likely theyare to agree with a negative statement about Islam? Assume parametric assumptions are met. A. Is this a relationship test or a difference test? Explain your rationale. B.Due to the alarming cases of Covid-19, a researcher wanted to study the characteristics of the patients in NCR infected by the virus. Lilliefors, a researcher, considered the following variables: M: age bracket (0-19, 20-39, 40-59, 60 and above) N: last country visited in the past 3 months O: number of days quarantined after manifestation of symptoms P: current status of the patient (mild, moderate, severe) 6. To answer the objective of the study, Lilliefors used different data collection methods. First, she gathered information about the variables of interest by letting the patients answer a self-administered questionnaire. Second, to supplement the data she gathered, she collected the sociodemographic profile of the patients using the data from the Department of Health. The methods of data collection used by Lilliefors are ________. A. objective and subjective, respectively B. subjective and objective, respectively C. objective and use of existing records, respectively…Each year, more than 2 million people in the United States become infected with bacteria that are resistant to antibiotics. In particular, the Centers of Disease Control and Prevention have launched studies of drug-resistant gonorrhea.† Suppose that, of 189 cases tested in a certain state, 12 were found to be drug-resistant. Suppose also that, of 429 cases tested in another state, 8 were found to be drug-resistant. Do these data suggest a statistically significant difference between the proportions of drug-resistant cases in the two states? Use a 0.02 level of significance. (Let p1 = the population proportion of drug-resistant cases in the first state, and let p2 = the population proportion of drug resistant cases in the second state.) State the null and alternative hypotheses. (Enter != for ≠ as needed.) H0: ______ Ha: ______ Find the value of the test statistic. (Round your answer to two decimal places.) = What is the p-value?

- Based on advancements in drug therapy, a pharmaceutical company is developing Resithan, a new treatment for depression. A medical researcher for the company is studying the effectiveness of Resithan as compared to their existing drug, Exemor. A random sample of 461 depressed individuals is selected and treated with Resithan, and 172 find relief from their depression. A random sample of 419 depressed individuals is independently selected from the first sample and treated with Exemor, and 121 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.01 level of significance, that the proportion p1 of all depressed individuals taking Resithan who find relief from depression is greater than the proportion p2 of all depressed individuals taking Exemor who find relief from depression? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as…The Ministry of Health Malaysia is interested in the post-shot side effects of a particular Covid-19 vaccine on teenagers. The manufacturer of a particular vaccine claims that 50% of the second dose recipients would develop mild side effects than others. The Covid-19 working group performed a hypothesis test to determine if the claimed percentage by the vaccine manufacturer is trustworthy. They sampled 100 teenage vaccine recipients and found that 53 of the recipients had mild side effects after their second dose of Covid-19 vaccine administration. A 5% level of significance was chosen for the hypothesis test. iv. Illustrate the level of significance and the critical value in a graph.In the Spring and Summer of 2020, mass protests erupted across the US in response to police violence against African Americans. At the same time, the US was experiencing a COVID-19 pandemic. Many public health experts wondered whether participating in these protests (exposure) would be associated with being diagnosed with COVID-19 (outcome). Imagine you have been hired to draft a plan to study this potential association. Which study design would you choose? (Almost any design is okay). Explain the factors that influenced why you selected that one. Include some of the benefits/drawbacks of your selected study design and the benefits/drawbacks of the study designs you did not select. Write your research question and make a hypothesis about the results. Briefly describe how you would conduct your study, including Recruitment strategy and a number of participants (Be sure you have people in all 4 boxes of the 2x2 table!) Measure of association to be used (RR/OR) Potential confounding…
- In the current pandemic, researchers are working on creating antibody tests to determine which individuals have already had an infection caused by the COVID-19 virus. If someone has been infected, then they will have certain antibodies in their system and the hope is that a highly accurate test can be created to detect these antibodies. Assume a researcher creates a new antibody test, which for individuals who are known to have had the infection in the past and thus truly have the COVID-19 antibodies, gives a positive result 95% of the time. This same test gives a negative result 90% of time for people who do not have the antibodies. Assume that COVID-19 has affected 5% of the population in the region of interest. What is the probability someone has NOT been infected previously given that their antibody test result comes back positive? [four decimals]Based on advancements in drug therapy, a pharmaceutical company is developing Resithan, a new treatment for depression. A medical researcher for the company is studying the effectiveness of Resithan as compared to their existing drug, Exemor. A random sample of 422 depressed individuals is selected and treated with Resithan, and 167 find relief from their depression. A random sample of 579 depressed individuals is independently selected from the first sample and treated with Exemor, and 203 find relief from their depression. Based on the medical researcher's study can we conclude, at the 0.01 level of significance, that the proportion p₁ of all depressed individuals taking Resithan who find relief from depression is greater than the proportion p₂ of all depressed individuals taking Exemor who find relief from depression? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in…Xu and Garcia (2008)conducted a research study demonstrating that 8-month-old infants appear to recognize which samples are likely to be obtained from a population and which are not. In the study, the infants watched as a sample of n = 5 ping-pong balls was selected from a large box. In one condition, the sample consisted of 1 red ball and 4 white balls. After the sample was selected, the front panel of the box was removed to reveal the contents. In the expected condition, the box contained primarily white balls like the sample, and the infants looked at it for an average of M = 7.5 seconds. In the unexpected condition, the box had primarily red balls, unlike the sample, and the infants looked at it for M = 9.9. The researchers interpreted the results as demonstrating that the infants found the unexpected result surprising and, therefore, more interesting than the expected result. Assuming that the standard error for both means is σM = 1 second, draw a bar graph showing the two sample…
