Utilizing the following Christmas Tree production function that you had completed in Homework 2 that includes output and cost information for a firm, respond to the questions given, assuming the firm is a perfectly competitive firm:

a.) Assume that the selling price for Christmas Trees is $80/tree. What would be the approximate profit-maximizing rate of output that you would want to produce? Would the firm be generating profit above all costs at that selling price? Why or Why not?

b.)If the price of Christmas Trees drops to $60/tree, approximately how many trees would now be produced for the optimum level? Are you making a profit above all costs at $60/tree? Why or Why not?

c.)At what price would be the short-run break-even point? At what price would be the firm’s short-run shutdown point?

A doctor claims that the number of births by day of the week is uniformly distributed. To test this claim, you randomly select 700 births from a recent year and record the day of the week on which each takes place. The table shows the results.

Test the doctor's claim at the significance level a=0.05.

a) What is the assumed proportion of births in each day?(in fractions)

b) State H0 and Ha.

c) What is the degrees of freedom of the test?

d) Calculate the x^2 test statistic.

e) Decide whether to reject the null hypothesis.

g) Interpret the decision in the context of the original claim.

The programming language that is being used here is JAVA, below I have my code that is supposed to fulfill the TO-DO's of each segment. This code in particular has not passed 3 specific tests. Below the code, the tests that failed will be written in bold with what was expected and what was outputted. Please correct the mistakes that I seem to be making if you can. Thank you kindly.

OverView:

For this project, you will develop a game program called Stick, Water. Fire- a version of the game Rock, Paper, Scissors. The user plays against the computer. You will use conditional expressions in several ways in this project. Primarily, you will write code to implement the game rules using conditional statements. You will also utilize Java’s ​Random​ class to generate random outcomes used in the game for the computer’s choice. The ​Random ​class can be seeded so that development and testing can be more easily done. Another aspect of this project is the use of a private method in a class. Private methods are used only within a class to help other methods with their calculations.

Program Interaction:

Our goal is to make a fun and interactive game for users. The user will be able to enter their choice of Stick, Water, or Fire. The computer will also make a choice, and the winner will be chosen based on the following three rules:

1. Stick beats Water by floating on top of it

2. Water beats Fire by putting it out

3. Fire beats Stick by burning it

The user is prompted to enter S, W or F (Note that the input can be upper or lower case). The computer then makes its choice (randomly generated) and the program applies the game rules to the user and computer’s choices.
The user and computer’s scores are recorded as well as the number of rounds played.

Ties result in no increase in either user or computer scores, but the round is counted.

A sample of the program’s behavior is given below. This is how the program should function when you have it working:

======Code===============

import java.util.Random;

/* This class ecapsulates the state and logic required to play the
Stick, Water, Fire game. The game is played between a user and the computer.
A user enters their choice, either S for stick, F for fire, W for water, and
the computer generates one of these choices at random- all equally likely.
The two choices are evaluated according to the rules of the game and the winner
is declared.

Rules of the game:
S beats W
W beats F
F beats S
no winner on a tie.

Each round is executed by the playRound method. In addition to generating the computer
choice and evaluating the two choices, this class also keeps track of the user and computer
scores, the number of wins, and the total number of rounds that have been played. In the case
of a tie, neither score is updated, but the number of rounds is incremented.

NOTE: Do not modify any of the code that is provided in the starter project. Additional instance variables and methods
are not required to make the program work correctly, but you may add them if you wish as long as
you fulfill the project requirements.

Don Hawk Furnishings sells a variety of decorative pieces including a variety of candle holders. The business began the second quarter (April to June) of 2018 with 15 (Alanea) candle holders at a total cost of $108,750. The following transactions relating to the “Alanea” candle holders were completed during the quarter.

April 7 90 candle holders were purchased at a cost of $6,850 each. In addition the business paid freight charges of $800 cash on each candle holder to have the inventory shipped from the point of purchase to their warehouse.

April 30 The sales for April were 75 candle holders which yielded total sales revenue of $803,250. ( 15 of these units were sold on account to longstanding customers of the business)

May 6 A new batch of 80 candle holders was purchased at a total cost of $654,800

May 9 Upon inspection of the candle holders purchased on May 6, five (5) of the units were found to be defective and were returned to the supplier.

May 31 During the month 62 of the decorative pieces were sold at a price of $11,450 each.

June 5 A customer, to whom 7 of the candle holders were sold during the first business day of May, returned 3 of the candle holders, as they were of another make & model.

June 14 Owing to an increased demand, a further 110 candle holders were purchased at a cost of $9,000 each; the supplier gave a 3% quantity discount on the purchase.

June 30 116 candle holders were sold during June at a unit selling price of $12,250.

June 30 An actual count of inventory was carried out at the close of business which revealed that there were 36 pieces of the Alanea brand of merchandise in the store room. Unless otherwise stated, assume that all purchases were on account and received on the dates stated.

Required:

(A) Prepare a perpetual inventory record for this merchandise, using the first in, first out (FIFO) method of inventory valuation to determine the company’s cost of goods sold for the quarter and the value of ending.

(B) Given that selling, distribution and administrative costs associated with the Alanea brand of candle holders for the quarter were $27,255, $42,400 and $145,600 respectively, prepare an income statement for Don Hawk Furnishings (Alanea) for the quarter ended June 30, 2018.   

(C) Journalize the transactions for the month of April, assuming the company uses a:

- Periodic inventory system

- Perpetual inventory system

(D) The manager of the business, Don Hawk, has stated that his objective is to cut back on his tax liability as much as possible and is of the view that the FIFO method would be best. Do you agree with Don? Explain your answer clearly distinguishing between the first in, first out (FIFO) and last in, first out (LIFO) methods of inventory valuation.
