V+Consider a closed economy with fixed prices and wages. Suppose the consumption
function is given by
? = 50 + 0.5?
?
where C is consumption and ?
?
is disposable income. The investment function is
given by
? = 30 − 5?
where I is investment and r is the interest rate. The demand for money is given by
?/? = 200 + 2? − ℎ?
where M is the amount of money demanded, P is the price level, and h is a parameter
measuring the sensitivity of money demand to the interest rate. Assume that the
price level is fixed at P = 1.
(a) Assume that h=20. If government spending is G=20, taxes are T=10, and
the money supply is M=300, find the equilibrium levels of output and the
interest rate.

(b) Now assume that government spending decreases to 10. What is the
multiplier? Is the effect of government spending on output increased or
decreased when h is larger? Explain your answer intuitively.

(c) Now suppose taxes decrease to 0. What is the multiplier? Will the
multiplier be different than your answer in part (b)? Explain intuitively.

i am having trouble with b and c. could you do them in detail mainly the multipliers

Problem

In 2012, at the beginning of California's most recent drought, 14% of front yards in Los Angeles County were drought tolerant. Note: A "drought tolerant" front yard is a yard consisting of artificial turf, rocks, or water efficient plants. A hydrologist believes that, due to landscaping rebate programs, the population proportion of drought-tolerant front yards in Los Angeles County has increased since 2012.

The hydrologist observes a random sample of 800 front yards from across Los Angeles County and finds that 140 out of the 800 front yards are drought tolerant.

Is there sufficient evidence to conclude that the population proportion of drought-tolerant front yards in Los Angeles County has increased since 2012? Use an α = 0.01 level of significance.

Question 1

State the null and alternative hypotheses (using symbols).

Question 2

Explain what it would mean for the hydrologist's study to make a Type I Error.

Question 3 (Optional)

Verify the requirements for this hypothesis test. Briefly show that each requirement is satisfied.

Question 4

Test the hypothesis using either the classical (test statistic) approach or the P-value approach. Show all steps to your approach. Then state whether you reject H 0 or do not reject H 0.

Question 5

Is there sufficient evidence to conclude that the population proportion of drought-tolerant front yards in Los Angeles County has increased since 2012? State your conclusion in one or two sentences.

You are working the afternoon shift in an inpatient psychiatric unit. The patients are in the day room
watching a movie when suddenly someone starts yelling. You and other staff rush to the day room to find
J.J., a 48-year-old male patient, crouched in the corner behind a chair, yelling at the other patients, "Get
down. Get down quick." You and the other staff are able to calm J.J. and the other patients and take J.J. to
his room. He apologizes for his outburst and explains to you that the movie brought back memories of
the Gulf War. He had forgotten where he was and thought he was in combat again. He describes to you
in detail the memory he had of being ambushed by the enemy and watching several of his comrades be
killed. You remember hearing in report that J.J. is a Gulf War veteran admitted with posttraumatic stress
disorder (PTSD ).
1. What are common causes of PTSD, and what is the most likely cause of J.J.'s condition?
2. Name three criteria that must be present for a diagnosis of PTSD.
3. What is the difference between PTSD and acute stress disorder?
4. Which symptom(s) of PTSD did J.J. most likely experience?

5. What therapeutic measures can be done to help J.J. during your shift this afternoon?

While you are in J.J.'s room, he states that he would like to rest for a while, and he requests something to
"calm his nerves." You check his medical record see these PRN (as needed) medications listed.
Chart View
PRN Medications
Acetaminophen (Tylenol) 650 mg PO every 6 hours prn pain or fever
Alprazolam (Xanax) orally dissolving tablet, 0.5 mg by mouth every 4 hr prn anxiety
Zolpidem (Ambien) extended release, 12.5 mg PO at bedtime if needed
6. Which medication is most appropriate to administer at this time? Explain.
7. What are the adverse effects of long-term use of benzodiazepine anxiolytics?
8. You decide to notify J.J.'s physician about his reaction to the movie. The physician writes an
order to start paroxetine (Paxil). How does this medication differ from alprazolam?

9. Which of these are potential side effects of paroxetine? Select all that apply.
a. Nausea
b. Constipation
c. Postural hypotension
d. Headache
e. Tinnitus

J.J. asks you whether there are other things he can do, in addition to medications, to help his anxiety. He
tells you that he's heard about relaxation therapy and wants to hear more about it.
10. What would you discuss with J.J. about relaxation therapy?
11. To what other treatment modalities could J.J. be referred after his hospitalization to help treat
his PTSD and related problems?

1. Diagram a purely (product market) competitive firm in long-run equilibrium. Be sure to show both the market and the representative firm. Next, on the same diagram, show what happens to the market and the representative firm if the market demand for the product falls dramatically, for instance, due to bad press. Briefly explain your conclusions.

Please show me your thought process. Please explain it as if you are telling it to someone who has no clue about economics.

To be able to conduct research for a study about the question “Would a person that works out and live a physically active life tend to have a longer life span than a person that isn’t physically active?” Please answer the following questions:

Most organizations are just scratching the surface of what they can learn and accomplish through the analysis of unstructured text. Opportunities for large and small businesses, as well as applications, are expanding. How can text analytics be applied to solve today’s business problems? What are some of the challenges organizations face when implementing text analytics solutions? Write your responses in detail with examples. Be sure to identify the source of your example in your posting. Your initial post should be of minimum 400 words.

Think of the meal you ate last night for dinner (if you do not eat dinners, think of what you had for lunch). Discuss in detail what happens to the food you ate in your mouth, stomach, small intestine, and large intestine. Was your dinner high in protein? Fats? Did it contain any carbohydrates? Fiber? Where were these nutrients digested chemically? Where do you think your dinner spent the most time and why? Be as specific (to your meal) as possible.
