A study was perform in the Albuquerque, New Mexico metropolitan area to evaluate the diagnostic accuracy of Prostate Specific Antigen (PSA) testing as a screening tool for detecting prostate cancer in community practice. Subjects were 2,620 men 40 years and older undergoing (PSA) testing and prostate biopsy. A total of 1,932 men tested positive with the initial PSA testing and among them cancer was detected in 800 subjects with a subsequent prostate biopsy. In addition, 130 cases of prostate cancer were detected among men who screened negative with the initial PSA test.

a) Using the information above, create a 2x2 table to assess the accuracy of the test.

b) Calculate and interpret the sensitivity of the PSA test.

c) What will be the specificity of this screening test? Calculate and interpret.

d) Calculate and interpret the predictive value positive of the PSA test.

e) Calculate and interpret the predictive value negative of the PSA test

Consider a casino game that an individual (Joe) wants to play. It costs him N dollars each time to play. He loves this game and wants to continue playing until he is either broke or he breaks the bank (wins all the money). The probability of winning is p; the probability of losing is q. These are fixed probability values every time the game is played.

Joe brought $M to the casino. Every time one plays you either lose the entrance fee ($N) or you win and are paid back D dollars.

(a) How much money does Joe expect to have after playing n times? Derive a formula for how much money he has.

(b) Suppose Joe starts with $100, p=0.3, q=0.7, N=$5, and D=$20. Is it likely that Joe will break the bank?

(c) If the answer to (b) is no, how many times is it likely that Joe can play this game before he is broke?

Bergamo Bay's computer system generated the following trial balance on December 31, 2019. The company’s manager knows something is wrong with the trial balance because it does not show any balance for Work in Process Inventory but does show a balance for the Factory Overhead account. In addition, the accrued factory payroll (Factory Wages Payable) has not been recorded.

After examining various files, the manager identifies the following six source documents that need to be processed to bring the accounting records up to date.

Jobs 402 and 404 are the only units in process at year-end. The predetermined overhead rate is 100% of direct labor cost.

3. Prepare a revised trial balance.

Could i get a walk trough how to solve these questions. Note that   is where the answer is meant to go.

Question 1

Say, instead of a separate variable (nItems), the number of items currently in the list are stored at index 0 in the array data, the actual values being stored starting at index 1. Complete the constructor that instantiates a list that can hold n values (excluding the item that holds the number of items currently in the list). That is, one should be able to add n values to the list before the need to grow it.

public class PackedArrayList {
public int[] data;

public PackedArrayList(int n) {
data = new int[  ];
data[0] =  ;
}
}

Question 2

Complete the body of method addEnsureCapacity in the following code:
public class MyArrayList {
public int[] data;
public int nItems;
public MyArrayList(int n) {
data = new int[n];
nItems = 0;
}
public void grow() {
//assume it increases capacity by 10
}
public boolean isFull() {
return (nItems == data.length);
}
public void addBasic(int val) {
data[nItems] = val;
nItems++;
}
public void addEnsureCapacity(int val) {
if(  == false) {
 ;
}
else {
 ;
addBasic(val);
}
}
}

   1. (a) A municipal bus system, when operating perfectly on schedule, provides a bus at any given bus stop every 30 min. You arrive at a random time at a bus stop. What is the average waiting time until the next bus arrives?

   2. (b) The busses become totally disorganized so that the spacing between busses is made random (assume that their arrival is a Poisson random process.) The same number of busses are still in operation. You again arrive at a bus stop at an arbitrary time. What is the average waiting time under these circumstances?

One method for producing hydrogen is to react coke (mostly solid carbon) with steam to make syngas, a mixture of CO and hydrogen

C(s) + H₂O(g) ⇌ CO(g) + H₂(g)     K_p = 0.45 at 900 K     ΔH = +131 kJ

What is the partial pressure of CO at equilibrium when 9.59 atm of H₂O(g) is heated with excess C(s) at 900 K?

After equilibrium is reached, CO(g) is added.

In which direction will the reaction shift?

Will the equilibrium constant, K, increase or decrease?

1. Company Z is evaluating a project that will increase annual sales by $150,000 and annual cash costs by $115,000. The project will initially require $98,000 in fixed assets that will be depreciated straight-line to a zero book value over the 4-year life of the project. The applicable tax rate is 32 percent. What is the NPV of this project if the required rate of return is 7% and the fixed assets required for the project will be scrapped at the end of the project?
