THIS QUESTION REQUIRES THE USE OF R STUDIO. ANY ANSWERS GIVEN THAT ARE NOT IN R STUDIO CODE WILL NOT SUFFICE. SOLVING WITHOUT THE USE OF R STUDIO IS NOT ACCEPTABLE.

The previous question was:

Annual salaries for a large company are approximately normally distributed with a mean of 49000 dollars and a standard deviation of 2000 dollars. One manager claims that all of his direct reports are paid "above the 75th percentile" for the company. What is the minimum dollar figure of employees working under this manager?

I used qnorm(o.75, 49000, 2000) to get an answer of $50,348.98 for the minimum dollar figure for employes under that manager.  

The current question:

Part 1: Create a neat, annotated, complete normal density plot representing the second part of the above question with the primary x-axis set to X.

I am struggling with the code for this question.  

Part 2: add a secondary x-axis to the plot from above, showing the Z values that correspond to the x-values of the first axis.  

Please show all code to obtain results.  

Fill in all the underlined spots on the spreadsheet with the data about Absorbance of Light for different Nitrate Levels. The goals are: 1) to compute the correlation and slope of the regression line by using the "SS formulas" and 2) to compute SSE, the sum of the squared "errors" (residuals).

Q3. (This question is based in R)
Now use the simulation ("X = rnorm(1000, mean = 10, sd = 2)", "Y = rnorm(1000, mean = 5, sd = 3)") to estimate the distribution of X+Y and create confidence intervals.

A) Form a set of Xs and Ys by repeating the individual experiment for B = 2000 times, where each experiment has n = 1000 samples. You may want to write a for loop and create two matrices "sample_X" and "sample_Y" to save those values. 

B) Calculate the mean of X+Y for each experiment and save it to a vector which has a length of B, and plot a histogram of these means. 

C) Now as we have a simulated sampling distribution of X+Y, calculate the 95% confidence interval for mean of X+Y (this can be done empirically). 

D) In the above example, we have fixed the sample size n and number of experiments B. Next, we want to change B and n, and see how the confidence interval will change. Please write a function to create confidence intervals for any B and n. 

E) Suppose the sample size n varies (100, 200, 300, .... , 1000) (fix B=2000) and the number of experiments B varies (1000, 2000, ... , 10000) (fix n=500). Plot your confidence intervals to compare the effect of changing the sample size n and changing the number of simulation replications B. What do you conclude? (Hint: Check function errbar() in Hmisc package for plot - library(Hmisc))

fix n, B varies

fix B, n varies

The town of Cypress Creek is preparing to go to war against the American government. To do this, it is building a giant satellite laser! To build the laser, the government of the town will resort to taxation to fund its expenditure. The initial economy of Cypress Creek can be expressed by the following agents:

Consumers, C = 25 + 0.95(Y-T)

Output, Y = 5000

Government expenditures, G = 2000

Taxation, T = 2000

Investors, I = 750-125r

Markets are fully competitive and the equilibrium condition for markets are:

Goods and service market: Y =C + I + G

Financial market: I = S

When it builds the Satellite, government and taxation change to  

Government expenditures, G = 4000

Taxation, T = 4000

Hank Scorpio, the towns' founder, announces that "even by increasing government spending and taxation, we are not worst off, as production has not changed!"

1. [2 points] check to make sure output does not change.
2. [2 points] find the consumption level in both scenario's (low and high government spending).
3. [3 points] who is paying for the burden of taxation? (how is this new spending/taxation being distributed between investors and consumers)
4. [2 points] as the government increases its spending (G from 2000 to 4000) why won't output change?

Hank Scorpio makes another announcement "People of North Haverbrook! We must all work together in this to crush the American Government - I implore you to save you wages! Don't spend!"

13. [2 points] by how much would consumers need to reduce their Marginal propensity to consume (MPC) such that the market clearing interest rate does not change?
