Dwight Donovan, the president of Benson Enterprises, is considering two investment opportunities. Because of limited resources, he will be able to invest in only one of them. Project A is to purchase a machine that will enable factory automation; the machine is expected to have a useful life of three years and no salvage value. Project B supports a training program that will improve the skills of employees operating the current equipment. Initial cash expenditures for Project A are $119,000 and for Project B are $44,000. The annual expected cash inflows are $47,012 for Project A and $18,319 for Project B. Both investments are expected to provide cash flow benefits for the next three years. Benson Enterprises’ cost of capital is 6 percent. (PV of $1 and PVA of $1) (Use appropriate factor(s) from the tables provided.) Compute the net present value of each project. Which project should be adopted based on the net present value approach? Compute the approximate internal rate of return of each project. Which one should be adopted based on the internal rate of return approach?

Insert the list of elements [11, 14, 16, 4, 7, 2, 23, 28, 19] in this order, into an initially empty AVL tree.     Show the details of the insertion process.       Note:    You must draw a different tree to show the result of each rotation involved. If an insertion requires a double rotation, you must show the result of each rotation separately.

Write a program, using functions, to print the lyrics of the song “Old MacDonald.” Your program should print the lyrics for five different animals, similar to the example verse below: Old MacDonald had a farm, Ee-igh, Ee-igh, Oh! And on that farm he had a cow, Ee-igh, Ee-igh, Oh! With a moo, moo here and a moo, moo there. Here a moo, there a moo, everywhere a moo, moo. Old MacDonald had a farm, Ee-igh, Ee-igh, Oh! Include a function that returns multiple values

QUESTION: Suppose you work in the quality assurance department of a chemical processing plant and it is your responsibility to ascertain whether the viscosity of a certain chemical remains within a prescribed limit. To that end you measure fluid samples using a viscometer.

a. The viscosities of a sample of 10 fluids processed during the day shift were measured to have the following results (Pa.s): 71, 45, 54, 75, 50, 49, 63, 55, 48, 50. Determine the range within which the true mean of the fluid samples from the day shift will be with a 95% confidence.

b. You then proceed to the measure the viscosities of a sample of 10 fluids processed during the night shift. You obtain the following measurements (Pa.s): 73, 45, 59, 75, 53, 58, 72, 54, 42, 52. Determine the range within which the true mean of the fluid samples from the night shift will be with a 95% confidence.

c. Can you state with a 95% probability that the viscosity of the fluid being produced during the day shift is different than the night shift? Frame your response in the form of a hypothesis test.

This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program).

(1) Extend the ItemToPurchase class per the following specifications:

Private fields

string itemDescription - Initialized in default constructor to "none"

Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0). (1 pt)

Public member methods

setDescription() mutator & getDescription() accessor (2 pts)

printItemCost() - Outputs the item name followed by the quantity, price, and subtotal

printItemDescription() - Outputs the item name and description

Ex. of printItemCost() output:

Bottled Water 10 @ $1 = $10

Ex. of printItemDescription() output:

Bottled Water: Deer Park, 12 oz.

(2) Create two new files:

ShoppingCart.java - Class definition

ShoppingCartManager.java - Contains main() method

Build the ShoppingCart class with the following specifications. Note: Some can be method stubs (empty methods) initially, to be completed in later steps.

Private fields

String customerName - Initialized in default constructor to "none"

String currentDate - Initialized in default constructor to "January 1, 2016"

ArrayList cartItems

Default constructor

Parameterized constructor which takes the customer name and date as parameters (1 pt)

getDate() accessor (1 pt)

addItem()

Adds an item to cartItems array. Has parameter ItemToPurchase. Does not return anything.

removeItem()

Removes item from cartItems array. Has a string (an item's name) parameter. Does not return anything.

If item name cannot be found, output this message: Item not found in cart. Nothing removed.

modifyItem()

Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. Does not return anything.

If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart.

If item cannot be found (by name) in cart, output this message: Item not found in cart. Nothing modified.

getNumItemsInCart() (2 pts)

Ex. of printTotal() output:

John Doe's Shopping Cart - February 1, 2016
Number of Items: 8

Nike Romaleos 2 @ $189 = $378

ABC Manufacturing Inc. ends the month with two jobs still in progress. Job 5 has​ $10,000 of​ materials, $2,000 of direct labor and​ $8,000 of manufacturing overhead allocated. Job 6 was​ $30,000 of​ materials, $2,000 of direct labor and​ $10,000 of manufacturing overhead allocated. The cost of goods sold for the month was​ $40,000 and of that​ 30% was overhead. There were no finished goods in stock as the month ends. If the manufacturing overhead is underallocated by​ $10,000, which of the following choices would be the correct way to prorate​ it, assuming the proration is based on the allocated overhead in the ending balances of​ work-in-process, finished​ goods, and cost of goods​ sold? (Round any allocation percentages to one decimal​ place, X.X%.)

A. Job 6 should be allocated another​ $6,000 of cost

B. Job 5 should be allocated another​ $6,000 of cost

C. Cost of goods sold should be reduced by​ $4,000

D. Cost of goods sold should be increased by​ $4,000
