This is a Matlab Exercise problem. Please create the Matlab code and figure for the following problem using problem specifications:

Plot x vs y when y=sin(x), y=cos(x), y=sin (2*x), and y=2*sin(x) when x = 1:0.1:10. Use 2 by 2 subplot, sin(x) is in location 1, cos(x) is in location 2, sin(2*x) is in location 3 and 2*sin(x) is in location 4.

The plot should have:

(1) x label = ‘x value’, y label = ‘y value’, legend ‘y=sin(x)’,’ y=cos(x)’,’ y=sin (2*x)’, ‘y= y=2*sin(x)’ and title = ‘x Vs. y’ under Font Name of Times New Roman, and Font Size of 14 pt. for all subplot location.

(2) For sine(x) use red solid line, for cos(x) use blue dashed line, for sin(2*x) use green dash-dot line, and for 2*sin(x) use solid line and RGB [0.5 0.2 0.2]

(3) Create minor grid for all subplot location.

Please attach editor code and the figure in your answer. Thank You!

A 2010 Pew Research poll asked 1,306 Americans "From what you've read and heard, is there solid evidence that the average temperature on earth has been getting warmer over the past few decades, or not?". The table below shows the distribution of responses by party and ideology, where the counts have been replaced with relative frequencies.

b) What is the probability that a randomly chosen respondent believes the earth is warming or is a liberal Democrat?  (please round to four decimal places)

c) What is the probability that a randomly chosen respondent believes the earth is warming given that he is a liberal Democrat?  (please round to four decimal places)

d) What is the probability that a randomly chosen respondent believes the earth is warming given that he is a conservative Republican?  (please round to four decimal places)

f) What is the probability that a randomly chosen respondent is a moderate/liberal Republican given that he does not believe that the earth is warming?  (please round to four decimal places)

A Fair Isaac Corporation (FICO) score is used by credit agencies such as banks to determine whether to lend money and the interest rate to charge. Its value ranges from 300 to 850 and if you have a score over 700, you are considered to be a "quality" credit risk. The mean credit score of average income earners in California is estimated by Fair Isaac to be 664. A recent survey of 47 high income earners in California had a mean FICO score of 677 and a standard deviation of s=60. Use a 0.05 significance level to test the claim that the mean FICO score of high income earners in California is equal to 664, the mean score of average income earners in California.

The test statistic is?: ["3.24", "2.88", "1.87", "2.27", "1.49"]           

Identify the range of the p-value: ["0.01 < P-value < 0.02", "0.1 < P-value < 0.2", "0.2 < P-value", "0.02 < P-value < 0.05", "P-value < 0.01", "0.05 < P-value < 0.1"]           

Based on this we?: ["Reject the null hypothesis", "Fail to reject the null hypothesis"]           

Conclusion: There ["does not", "does"] appear to be enough evidence to support the claim that the mean FICO score of high income earners in California is equal to 664, the mean score of average income earners in California.

Problem 16-01 (Algorithmic)

The management of Brinkley Corporation is interested in using simulation to estimate the profit per unit for a new product. The selling price for the product will be $45 per unit. Probability distributions for the purchase cost, the labor cost, and the transportation cost are estimated as follows:

1. Compute profit per unit for the base-case, worst-case, and best-case.
   
   Profit per unit for the base-case: $  
   
   Profit per unit for the worst-case: $  
   
   Profit per unit for the best-case: $  
   
2. Construct a simulation model to estimate the mean profit per unit. If required, round your answer to the nearest cent.
   
   Mean profit per unit = $  
   
3. Why is the simulation approach to risk analysis preferable to generating a variety of what-if scenarios?
   
   The input in the box below will not be graded, but may be reviewed and considered by your instructor.
   
   
   
4. Management believes the project may not be sustainable if the profit per unit is less than $4. Use simulation to estimate the probability the profit per unit will be less than $4. If required, round your answer to one decimal place.

Suppose the inflation rate is expected to be 6.3% next year, 4.15% the following year, and 3.65% thereafter. Assume that the real risk-free rate, r*, will remain at 2.3% and that maturity risk premiums on Treasury securities rise from zero on very short-term bonds (those that mature in a few days) to 0.2% for 1-year securities. Furthermore, maturity risk premiums increase 0.2% for each year to maturity, up to a limit of 1.0% on 5-year or longer-term T-bonds.

You are the manager of a healthcare facility that is considering different payment options for buying supplies for your facility. The annual charges for these supplies is $10,000 and the vendor is offering you three payment options to consider.

option 1: 3% discount if you make the full payment in 30 days.

option 2: quarterly payments at the beginning of each quarter with a service charge of $100 per quarter.

option 3: monthly payments at the beginning of each month with a service charge of 3% for each monthly payment.

Q1: Which of these three options provides the best value for money? Why?

Q2: Payments for these supplies are made from your bank account which has a current balance of $30,000 and earns monthly interest of 0.2%.

a. Which of these three options now provides the best value for money?

b. At what interest rate would you be indifferent between Options 1 and 2?

c. At what interest rate would you be indifferent between Options 2 and 3?

d. Consider the ending balances under each of these three options for interest rate ranging from 0.0% to 2.0%. Develop data tables to compute the ending balances for this range of interest (consider interest increments of 0.2%). Depict your results in a line graph.

Circle Class (This is in JAVA)

/**
 * Defines a basic shape with just area
 *
 * @author Jo Belle
 * @version 0.2 (10/05/2020)
 */
public class Shape{
    private double area;

    public Shape(){ area = 0.0; }
    public Shape( double a ){ this.area = a; }
    public void setArea( double a ){ area = a; }
    public double getArea(){ return area; }
    public String toString(){
        return "Shape:\n\tarea: " + area;
    }
}

/**
 * Create a simple Circle object
 *
 * @author Jo Belle
 * @version 0.2 (10/12/2020)
 */
public class ShapeDriver{
    public static void main( String[] args ){
        Circle cir = new Circle( );
        cir.setRadius( 5.0 );
        System.out.println( cir.toString() );
    }
}

Given the code above, write a Circle class (and save it in a file named Circle.java) that inherits from the Shape class. Include in your Circle class, a single private field double radius. Also include a method void setRadius(double r) (which also sets area) and a method double getRadius() (which also returns the current radius). Change the accessibility modifier for area in the Shape class to be more appropriate for a base class. Make sure that ShapeDriver's main() method executes and produces the following output:

Shape:
        area: 78.53981633974483
        radius: 5.0

Submit both your Circle.java and your Shape.java files.
