Explain at what point a person is considered "under arrest." Explain the difference between a stop and an arrest. Why might states authorize probable cause arrests for certain unwitnessed misdemeanors? How much force can be used by an officer when executing an arrest? How is it determined? Can you think of any times when you heard about "excessive use of force" and if so, how do you think the actions of a few influenced the perceptions of many regarding the police??

Please paraphrase this paragraph into a short summary..

Good philosophical thinking takes time. Progress in good critical thinking is often very slow. The process of critical thinking can’t be called successful if it efficiently maximizes its inputs and outputs in the shortest measure of time: We do not produce thoughts in the mind like widgets in a factory. The reason for this is because good critical think- ing often needs to uncover that which subtle, hard to discern at first, and easy to overlook. I define subtlety as ‘a small difference or a delicate detail which takes on greater importance the more it is contemplated.’ As a demonstration, think of how many ways you can utter the word ‘Yes’, and mean something different every time. This also underlines the importance of precision, as a good thinking habit. As another example: Think of how the colour planes in a painting by Piet Mondrian, such as his ‘Composition with Yellow, Blue, and Red’ have squares of white framed by black lines, but none of the white squares are exactly the same shade of white. You won’t notice this if you look at the painting for only a few seconds, or if you view a photo of the painting on your computer screen, and your monitor’s resolution isn’t precise enough to render the subtle differences. But it is the job of reason to uncover those subtleties and lay them out to be examined directly. And the search for those subtleties cannot be rushed.

Though the extent of its long-term impact is still unclear, it is increasingly believed by experts that the COVID-19 pandemic will change the world in a number of important ways. With respect to business and capitalism, COVID-19 poses a number of unique challenges that can already be observed. Based on this, please answer the following questions:

a. What assumptions of capitalism has COVID-19 fundamentally challenged? Pick any three assumptions of capitalism discussed in the course and explain how they are challenged by COVID-19. Use examples where possible. (9 points)

b. How are the debates around CSR, shareholders/stakeholder, short-term/long-term, and corporate power reflected in the COVID-19 pandemic? Pick any two debates discussed in the course and describe in detail how they are relevant to COVID-19. Use examples where possible. (8 points)

c. How will COVID-19 change business and capitalism? In this course we have discussed many of the key events in the recent history of capitalism (stock market crash of 1929, World War 2, OPEC oil shocks, financial crisis of 2008). How do you believe COVID-19 will change capitalism? What will change? What will stay the same? Why? Use examples where possible. (10 points)

An usher at a movie theater claims no more than half of all movie theater customers buy something at the refreshment stand. To test the claim, the usher observes a random sample of 80 people and finds that 47 of them buy something.

a) What is the Null Hypothesis and the Alternative Hypothesis for the usher's claim?

b) If we use a 0.01 significance level, what is the critical value for the test?

c) Calculate the value of the test statistic.

d) What is your decision about the null hypothesis and your conclusion about usher’s claim?

e) Calculate the p-value for this test.

1. A heater is used to heat 100 SCM of nitrogen in a rigid vessel from 26.85^oC  to 126.85^oC. Do energy balance and calculate heat duty Q (kJ) using data from Table A-2a,b,c and A18. State your assumption and explain your results.

1. Explain how liminality, cultural chasm and white supremacy are inter-related.

2. Start to connect with the reading. Use ONE example of your read material and connect it to one of the term. How is the term being described in the reading. You can't use bell hooks and cultural chasm because I already provided you an example in the online lecture. BUT you can use another one from hooks' essay if you find it.

3. Start thinking of experiential factors that contribute to the liminal state of Judith Ortiz Cofer and bell hooks. Identify 1 for EACH of the authors. Demonstrate that you read.

Complaints about weekday airline flights not being on time average about 15.17 complaints per month at airports in small U. S. cities. The local airport is proud to advertise that its average monthly on-time performance is superior to the national monthly average for small city airports. Since June 2003, a random sample of nine months reveals that the number of complaints regarding weekday flights not being on time at the local airport were: 9 10 12 13 14 15 15 16 17 Using the 0.05 significance level, does the data justify the local airport's claim?
