The number? H(t) of veterans from foreign wars who are homeless or at risk of becoming homeless can be approximated by the exponential? function,

H(t)=65(1.65)^t where t is the number of years since 2000.

?a) In what year were there 14,000 veterans who were homeless or at risk of becoming? homeless?

?b) What is the doubling time of homelessness among? veterans?

It has been determined, with 90% confidence, that the proportion of students who graduate from college are able to find a job in their field of study lies between 64% and 83%. Using this information answer the following questions.

Interpret this confidence interval in the context of this problem.
​​​​​​​​​​​​​​What would happen to this interval if the confidence level were to increase to 95%?

. A columnist for the Wall Street Journal observes: “No one collects money from those who benefit from the food control a wetland provides, or the nutrient recycling a forest does… In a nutshell, market failures help drive habitat loss.” What does the columnist mean by market failures? What does she mean by habitat loss? Explain why she believes one is causing the other. Illustrate your argument with a graph showing the market for land to be used for development.

Who are the inspiring leaders from healthcare and what makes them inspirational? Be sure to first offer a brief framework, based on relevant reference materials, that explore the concepts related to motivation, inspiration, and leadership.

The average starting salary of students who graduated from colleges of Business in 2009 was $48,400. A sample of 100 graduates of 2010 showed an average starting salary of $50,000. Assume the standard deviation of the population is known to be $8000. We want to determine whether or not there has been a significant increase in the starting salaries. Step 1. Statement of the hypothesis (1.5 marks) Step 2. Standardized test statistic formula (1 mark) Step 3. State the level of significance (1 mark) Step 4. Decision Rule (Draw a bell to show rejection zone) Step 5. Calculation of the statistic Step 6. Conclusion (1.5 marks)

Question 2

Harold is a 62 year old man who was found to be suffering from depression one year after a diagnosis of heart failure. Sertraline was added to his current prescription of irbesartan.

a) Compare the mechanism of action and clinical effects of these two drugs.

b) A move to a healthy lifestyle is recommended for people with heart failure. Discuss how the adverse effects of antidepress medication may interfere with this.

Explain the pathophysiology of acute renal failure in a patient who is suffering from severe haemorrhage resulting from a motor vehicle accident.

Suppose powerplant emissions are linked to morbidity and mortality in humans who live downwind from the powerplant. Suppose in recent years the daily load of emissions into the environment has averaged 4.0 million tons. Also suppose that since the generation of electricity is an important public service the Environmental Protection Agency is reluctant restrict electricity generation. A recent study compiled by the Green Party, an environmental organization, determined that the marginal benefits (in $’s per million tons) of abating emissions by are:

MB = 100 – 25A

A represents abated emissions in millions of tons.

While the Green Party believes that these benefits suggest that emissions should be eliminated entirely, an electricity production group has compiled information on abatement costs. They claim that the aggregate marginal cost function for pollution abatement is:

MAC = 10 + 20A

What would the net social benefits be under the Green Party's solution above? What would be the net social benefits under an economically optimal solution?

Suppose you were a policy-maker and you wanted to set a tax. What tax would you set for each ton of emissions pollution (taxes will be given in $’s per ton)?

Consider a worker who is planning to retire five years from now and is thinking about not working for the next year and instead completing a one-year Master’s program. If they do not complete the program, they will earn $C one year from now, $C two years from now, and so on through five years from now. If they complete the program, they will pay $A one year from now and then earn $B each of the subsequent four years. Assume the worker’s only concern is their financial well-being.
