(b) Professor GeniusAtCalculus has two lecture sections (A and B) of the same 4th year Advanced Calculus (AMA 4301) course in Semester 2. She wants to investigate whether section A students maybe ”smarter” than section B students by comparing their perfor- mances in the midterm test. A random sample of 12 students were taken from section A, with mean midterm test score of 78.8 and standard deviation 8.5; and a random sample of 9 students were taken from section B, with mean midterm test score of 86 and standard deviation 9.3. Assume the population standard deviations of midterm test scores for both sections are the same. Construct the 90% confidence interval for the difference in midterm test scores of the two sections. Based on the sample midterm test scores from the two sections, can Professor GeniusAtCalculus conclude that there is any evidence that one section of students are ”smarter” than the other section? Justify your conclusions.

(c) The COVID-19 (coronavirus) mortality rate of a country is defined as the ratio of the number of deaths due to COVID-19 divided by the number of (confirmed) cases of COVID-19 in that country. Suppose we want to investigate if there is any difference between the COVID-19 mortality rate in the US and the UK. On April 18, 2020, out of a sample of 671,493 cases of COVID-19 in the US, there was 33,288 deaths; and out of a sample of 109,754 cases of COVID-19 in the UK, there was 14,606 deaths. What is the 92% confidence interval in the true difference in the mortality rates between the two countries? What can you conclude about the difference in the mortality rates between the US and the UK? Justify your conclusions. [8 marks]

a. The price elasticity of a good is -4.2. What does this mean? What would happen to the total revenue collected if prices were to increase by 10% and explain your answer.

b. The income elasticity of a good is 0.25. What does this mean? What can we conclude about this good and explain how you came to this conclusion?

c. The cross-price elasticity of a good is -1.5. What does this mean? What can we conclude about this good and explain how you came to this conclusion?

Consider a gas of diatomic molecules at temperature T, each with moment of inertia I. If Eg is the ground-state energy and Eex is the energy of an excited state, then the Maxwell-Boltzmann distribution predicts that the ratio of the number of molecules in the two states is nex ng = e −(Eex−Eg)/kBT . (1) a) Suppose we consider the excited state to be the ℓth rotational energy level, and the ground state to be ℓ = 0. Show that the ratio in equation (1) is equal to nℓ n0 = (2ℓ + 1)e −[ℓ(ℓ+1)¯h 2 ]/(2IkBT) . (Hint: the ℓth level contains multiple different states with different values of mℓ, all with the same energy. How many different values of mℓ are there for a given value of ℓ?) b) The moment of inertia of the carbon monoxide (CO) molecule is 1.449×10−46 kg·m2 . Use this to determine the numerical value of the ratio nℓ/n0 for a gas of CO molecules at a temperature of 300 K, for the following cases: (i) ℓ = 1 (ii) ℓ = 2 (iii) ℓ = 10 (iv) ℓ = 20 (v) ℓ = 50 c) Comment on your results from part (b). What do you see happening to the ratio as ℓ increases? Why does this happen? What does it tell us about the physical system?

In what ways has learning about psychology changed the way you feel about the discipline? What information in this class had the greatest impact on the way you think about psychology? How will you apply this new knowledge in the future? Do you think it is necessary for a person in your field of study to learn psychology and neuroscience? Explain your answer.

Graphically illustrate the labor market’s situation in case of a minimum wage enforcement. Discuss with at least 200 words.

its my question and explain in detail please because I don't understand very well and please do not write HANDWRITE because I don't understand your HANDWRITING

thanks a lot

We define economic exposure as the impact of exchange rate fluctuations on a firm’s future

earnings, cash flows and foreign investments. Explain in detail how you would restructure your MNC operating in Iraq and Kuwait to reduce economic exposure. (HOw MNC is able to reduce economic exposure in unstable environment?)

You are assigned the task of determining the bacterial density of newly-grown culture. You decide that you will analyze the sample with two methods, spectrophotometry and dilution plating. Your results show the sample tested using spectrophotometry had a bacteria density that was roughly ten folds that of the plated sample. Please explain in detail.

Question 2 (300-500 words)
Every society, regardless of its wealth and power, must make certain choices
about production and distribution. Specifically, every society faces three basic
economic decisions:
What goods and services to produce and in what quantities?
How to produce these goods and services, or how to use the economy's
resources?
Who gets these goods and services
Briefly explain how these questions are answered in your country. How does the
availability of resources in your country influence the economic decisions fo individuals,
organizations, and government?
