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.)

3. 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.

(Round up to nearest four decimal place.)

The corona virus pandemic has been, and will be, very costly to federal, state, and local governments as well as to businesses and to consumers. According to the Congressional Budget Office (2020):

CBO expects that the economy will contract sharply during the second quarter of 2020 as a result of the continued disruption of commerce stemming from the spread of the novel coronavirus. The following are CBO’s very preliminary estimates, which are based on information about the economy that was available through this morning and which include the effects of an economic boost from recently enacted legislation.

• Gross domestic product is expected to decline by more than 7 percent during the second quarter. If that happened, the decline in the annualized growth rate reported by the Bureau of Economic Analysis would be about four times larger and would exceed 28 percent. Those declines could be much larger, however.
• The unemployment rate is expected to exceed 10 percent during the second quarter, in part reflecting the 3.3 million new unemployment insurance claims reported on March 26 and the 6.6 million new claims reported this morning. (The number of new claims was about 10 times larger this morning than it had been in any single week during the recession from 2007 to 2009.)
• Interest rates on 10-year Treasury notes are expected to be below 1 percent during the second quarter as a result of the Federal Reserve’s actions and market conditions. (Swagel, 2020, para. 1)

How will the decline in GDP and the rise in unemployment, and low interest rates affect federal, state, and local governments?

Answer the following questions to complete Homework

1. Use PubMed or another abstract database  to find an academic journal article on a health topic of interest to you. Read the article to find the answers to these questions: (a) What was the main study question? (b) Who participated in the study, where did it take place, and when was it conducted? (c) What study design was used? and (d) What was the answer to the main study question?

2. Find a recent news story from the popular press about a newly released health research report. Look up and read the scientific article on which the news report was based. Was the news story accurate? Did it leave out any critical information?

3. Do you identify with a particular ethnic group? Do you know of any health conditions that you are at special risk for because of your ethnic background? Are these conditions genetic? Are they related to health behaviors?

4. What are some of the conditions related to poverty that increase the risk of infectious diseases? Noncommunicable disease? Neuropsychiatric disorders? Injuries?

In this exercise, you will calculate and graph confidence intervals that arise from many samples of the same size drawn from the same population. The aim of the exercise is for you to see what the confidence level means. In this exercise, we will use 95% confidence.

(1) The population will consist of the four values: 5, 10, 15, 50. Enter the data in your calculator and get the mean and population standard deviation.

I am having trouble with this question. My teacher gave us the answers but it doesn't show the work. The correct answers are mean= 20 and population standard deviation= 17.68

(TI-84 calc) When I try and solve this what I do is I put 5, 10, 15, and 50 all in the L1 data in my calculator. After that I do a TInterval test with C-level as 0.95 and List as L1 and press calculate. I end up getting 20 for my mean but Sx= 20.4124... when it should be 17.68. Am I going at this the wrong way and getting the mean just by coincidence?  

There is a famous quote often attributed to Albert Einstein that says:

“No amount of experimentation can ever prove me right; a single experiment can prove me wrong.”

There is some dispute about whether Einstein ever said this, but it might reflect his sentiments as more accurately cited in the book Mathematical Problems in Elasticity (Remigio Russo 1996):

“At this time the anti-relativity clique in Germany […] published a book called 100 Authors Against Einstein. Einstein informed that press that if relativity was wrong they would only need one author.”

Each quote captures an important aspect of the Popperian hypothetico-deductive account of science: knowledge comes from experimental falsification of a hypothesis rather than from experimental confirmation of one.

QUESTION: Explain how an inductivist might respond to this claim regarding falsification and knowledge. Do you agree with this response? Explain and justify your answer. In doing so, consider to what extent inductivists and Popperians have mutually exclusive ideals of what makes science rational, or whether they are, in some way, complementary.

Criminal Justice Statistics

The current COVID-19 Pandemic is threatening the health of all people and the world economy. During a recent press conference members from the White House Coronavirus Team identified a pattern suggesting that Black and American Indian individuals, while not more or less likely to be infected with COVID-19, tend to have more severe outcomes when infected. In other words, Black and American Indian individuals (as a group) express more severe symptoms and higher rates of morbidity than individuals of other races or ethnicities. There is no evidence at this time of a genetic component.

Using readily available sources identify and evaluate the possible causes of this increased severity and morbidity among these individuals. Include statistical information (comparing morbidity rates among various racial groups) in your response. Limit your discussion to bona fide scientific inquiries from actual medical professionals rather than editorial comments or conjecture. You may also want to consider that this same pattern tends to exist in other forms of medical maladies.
