Exhibit 2:

Current statistics show that, about 5% of the patients who are infected with the Novel Coronavirus are in serious or critical condition, and need ventilators and oxygen facilities. Suppose this is the population proportion. (The questions related to this Exhibit are designed so that you can see how statistical analyses can be used to fight against pandemics.)

1. Refer to Exhibit 2. Assume that in the City of Gotham, in the first week of outbreak, 256 citizens are tested positive for COVID-19. At least how many ventilators should be prepared to meet the possible demand. (Round up to the nearest integer that is larger than the result.)

2. Refer to Exhibit 2. Suppose the No. 1 district of the City of Gotham has 8100 residents living in it. If you were the head of the health department of the No. 1 district. To cope with the possible all-infection outbreak of COVID-19 in your district, you prepared 600 ventilators. Assuming in the worst case scenario, what is the probability that your prepared medical equipments are overwhelmed by the serious conditioned patients who are in need of the ventilators? (Round up to nearest four decimal place.)

Current estimates are that somewhere between 1% and 5% of the U.S. population hasbeen infected with Covid-19. A serological test for Covid-19 is supposed to determine if a personhas antibodies for that virus, which would indicate a previous infection. Some claim that if a persontests positive, then the person should be able to return to normal activity since they would haveimmunity (though whether an infected person develops immunity seems to be currently unknown).One particular test has a “specificity” of 95.6%,...

Exhibit Symptom of COVID-19 Study shows that about 70% of the COVID-19 patients have a dry cough (which does not bring up any mucus or phlegm). To use hypothesis testing method to check the credibility of this study, you randomly surveyed 25 patients of COVID-19 and 18 of them answered that they are having dry cough. 1. Refer to Exhibit Symptom of COVID-19. What is the value of the test statistics? 2. Refer to Exhibit Symptom of COVID-19. Which of...

People infected with SARS- CoV-2 (the coronavirus that causes COVID-19) can show an array of different symptoms and complications, ranging from mild to severe. Researchers are working to develop both prevention and treatment, including vaccines and antibody injections. Vaccines introduce antigens from viruses, without introducing the infectious virus itself. How/why do vaccines act as prevention rather than treatment? Be sure to talk about the types of cells and immune responses that vaccines are targeting, and why targeting these cells and...
