2. An important debate among macroeconomists concerned the interest rate elasticity of money demand. Monetarists believed that money demand was very sensitive to interest rate changes, while Keynesians believed that money demand was insensitive to interest rate changes.
   1. Show how different assumptions about the interest rate elasticity of money demand affect the slope of the LM curve. To do this, derive the LM curve for both Keynesians and monetarists on the same set of diagrams so we can visualize the differences.
   2. Given what you find in (a), which school of thought believed that a tax cut would have a stronger impact on aggregate output? Illustrate by drawing a new IS-LM diagram with both a monetarist and Keynesian LM curve drawn on it. Explain your logic in detail.

Most people have several jobs over their lifetimes. Give a brief description of two jobs . Without revealing private information, explain if the job was part-time or full-time and address the following questions.

• What skills were required to perform your best?

  • To what extent were agility, problem solving, and technology skills necessary for success?

• What skills did you learn in each job?

  • How did learning these skills contribute to improving your ability to be effective in your work?

• Did these new skills increase your human capital?

• If you haven’t yet had a job, describe the type of career you hope to have after finishing school.

  • How will agility, problem solving, and technology skills be a vital part of your success in this type of career?

Jones Co. is in a technology-intensive industry. Recently, one of its competitors introduced a new product with technology that might render obsolete some of Jones’s inventory. The accounting staff wants to follow the appropriate authoritative literature in determining the accounting for this significant market event. Instructions If your school has a subscription to the FASB Codification, log in and prepare responses to the following. Provide Codification references for your responses. a.   Identify the primary authoritative guidance for the accounting for inventories. What is the predecessor literature?  

b.   List three types of goods that are classified as inventory. What characteristic will automatically exclude an item from being classified as inventory?  

c.   Define “market” as used in the phrase “lower-of-cost-or-market.”  

d.   Explain when it is acceptable to state inventory above cost and which industries allow this practice.

Identify the most relevant source of bias in each situation. a. A survey asks the following: Should the death penalty be permitted if innocent people might die? b. A study seeks to investigate whether a new pain medication is safe to market to the public. They test by randomly selecting 300 people who identify as men from a set of volunteers. c. A survey asks how many sexual partners a person has had in the last year. d. A radio station asks listeners to phone in their response to a daily poll. e. A substitute teacher wants to know how students in the class did on their last test. The teacher asks the 10 students sitting in the front row to state their latest test score.
f. High school students are asked if they have consumed alcohol in the last two weeks.

In 1995, the Educational Testing Service in Princeton, New Jersey (which administers SAT exam) re-centered the scores so that the overall mean would be approximately 1,000 in the combined math and verbal scores for a “large standardized group”. In 1996, approximately 1.1 million college-bound high school students took the exam and registered a mean score of 1,013, with a standard deviation of 222. About 40 percent of these students’ scores were between 900 and 1,100.
a) Based on this estimate, what is the probability that of 10 randomly selected students, less than four will be between 900 and 1,100?
b) What is the probability that more than four students will be in this range? What is the probability that exactly four students will be in this range?
c) What is the probability that between three and five students will range between 900 and 1,100?

Write in Java

1. Modify the parent class (Plant) by adding the following abstract methods:(The class give in the end of question)
   1. a method to return the botanical (Latin) name of the plant
   2. a method that describes how the plant is used by humans (as food, to build houses, etc)
2. Add a Vegetable class with a flavor variable (sweet, salty, tart, etc) and 2 methods that return the following information:
   1. list 2 dishes (meals) that the vegetable can be used in
   2. where this vegetable is grown

The Vegetable class should have the usual constructors (default and parameterized), get (accessor) and set (mutator) methods for each attribute, and a toString method

Child classes should call parent methods whenever possible to minimize code duplication.

The driver program must test all the methods in the Vegetable class, and show that the new methods added to the Plant class can be called by each of the child classes. Include comments in your output to describe what you are testing, for example   System.out.println(“testing Plant toString, accessor and mutator”);. Print out some blank lines in the output to make it easier to read and understand what is being output.

public class Plant {
  
private String name;
private String lifespan;

public Plant(){
name = "no name";
lifespan = "do not know";
