Suppose Liam's Kitchen, a restaurant,: serves two items: hamburgers and french fries. With all employees working diligently, the restaurant can produce these combinations each hour.

Type of Product:   Production Alternatives

A B C D E

Burgers 0 10 20 30 60

Fry Bags 100 90 70 40 0

Calculate the opportunity costs of moving from one point to each of the others: Provide the answers after showing all work, and explain if theses costs are constant. What would it mean if the kitchen was actually making 35 Burgers and 45 Fries from Fry Bags? What would it mean if the kitchen was actually making 15 Burgers and 70 Fries from fry bags?

(Rubric: 12.5 points - 1) calculate the opportunity costs and show the work.; 2) Explain the 35-45 question; 3) Answer whether the opportunity costs are fixed or not; and 4) Explain the 15-75 question. 10 points - one of the two explanations is only a "word" not a sentence, and/or one of the points isn't identified. May not be some calculations. 8 points - Neither explanation is a complete sentence, and some of the points aren't identified. May not be many calculations. 6.25 points or less points - This is a failing score for the question. The answer is worse than that required for 8 points.)   

The following income statement items appeared on the adjusted trial balance of Foxworthy Corporation for the year ended December 31, 2018 ($ in 000s): sales revenue, $21,600; cost of goods sold, $14,150; selling expenses, $2,230; general and administrative expenses, $1,130; dividend revenue from investments, $130; interest expense, $230. Income taxes have not yet been accrued. The company’s income tax rate is 40% on all items of income or loss. These revenue and expense items appear in the company’s income statement every year. The company’s controller, however, has asked for your help in determining the appropriate treatment of the following nonrecurring transactions that also occurred during 2018 ($ in 000s). All transactions are material in amount.

1. Investments were sold during the year at a loss of $230. Foxworthy also had unrealized holding losses of $130 for the year on investments.
2. One of the company’s factories was closed during the year. Restructuring costs incurred were $1,300.
3. During the year, Foxworthy completed the sale of one of its operating divisions that qualifies as a component of the entity according to GAAP regarding discontinued operations. The division had incurred operating income of $730 in 2018 prior to the sale, and its assets were sold at a loss of $1,940.
4. A positive foreign currency translation adjustment for the year totaled $670.

Required:

Prepare Foxworthy’s single, continuous statement of comprehensive income for 2018, including earnings per share disclosures. Use a multiple-step income statement format. Two million shares of common stock were outstanding throughout the year. (Enter your answers in thousands of dollars, except earnings per share. Amounts to be deducted should be indicated with a minus sign. Round EPS answers to 2 decimal places.)

Using the below question and values how do you calculate the standard deviation without using a calculator (by hand) of (s1^2/n1+s2^2/n2) with the standard deviation answer being 1.4938 and 1.1361
/sqrt(1.4938^2/10 + 1.1361^2/10)
Choose two competing store and compare the prices of 10 items at both stores. Preform a two-sample hypothesis test to try an prove if one store is more expensive than the other based on your sample. Store A item #1-$5.49, #2 $3.77, #3 $0.87, #4 $3.29, #5 $4.79, #6 $1.99, #7 $1.33, #8 $2.19, #9 $2.79, #10 $3.99 Store B items #1 $4.59, #2 3.99, #3 $1.79,  #4 $2.99, #5 $4.59, # $1.79, #7 $1.99, #8 $2.19, #9 $2.79, #10 $3.99

Hypothesis:
H0 ; mu1= mu2
HA: mu 1 > mu2

test statistics:

t = (x1-x2)/sqrt(s1^2/n1+s2^2/n2)
= (3.05 - 3.07)/sqrt(1.4938^2/10 + 1.1361^2/10)
= -0.0337

p value = .4872

FAil to reject the H0

A psychologist wants to determine whether speaking more than one language fluently has cognitive benefits. They conduct a study in which a total of 72 participants are tested on a task measuring cognitive control. Half the participants are male, and half are female and speak one, two, or three+ languages fluently. For a two-way ANOVA with SS_between = 148; SS_Language = 80; SS_Sex = 50; SS_total = 350, what can the psychologist conclude? Be sure to address all hypotheses. Assume the DV is continuous.

It has been suggested that the highest priority of retirees is travel. Thus, a study was conducted to investigate the differences in the length of stay of a trip for pre- and post-retirees. A sample of 696 travelers were asked how long they stayed on a typical trip. The observed results of the study are found below.  

With this information, construct a table of estimated expected values.

Now, with that information, determine whether the length of stay is independent of retirement using alpha = 0.01

a) chi squared =

b) Find the degrees of freedom:

c) Find the critical value:

d) The final conclusion is

A. There is not sufficient evidence to reject the null hypothesis that the length of stay is independent of retirement.

B. We can reject the null hypothesis that the length of stay is independent of retirement and accept the alternative hypothesis that the two are dependent.

Think about the sources of conflict that were identified through our class content on conflict. Choose two of those sources, and match each with what you believe is an appropriate conflict management style to utilize when resolving a conflict within that source. Defend and justify your discussion using examples.

When events occur in a time period (0, a) with regard to a Poisson process, it is well known that, conditioned on the total number of events k, the joint distribution of the times at with the events occur follows a uniform distribution in (0, a) k. That is, if Xi represents the arrival time of one of them, then Xi ∼ U(0, a) and it is independent of the other X’s.

1. If ten patients visit the Emergency Room (ER) of a hospital between 9 and 10, what is the probability that fifth of them reaches the ER before 9:30?

2. If ten patients visit the ER between 9 and 10, what is the probability that the first 3 of them arrive before 9:20, 4 of them between 9:20 and 9:40, and the last 3 of them after 9:40?

3. If two patients visit the ER of a hospital between 9 and 10, what is the conditional distribution of the time at which the second patient arrived at the ER given that the first patient arrived at time t1?

Simulating a random walk in two dimensions.

For this part, you will use a two-dimensional grid where the x axis goes from -50 to +50 and the y axis also goes from -50 to +50. The particle will start at the middle of the left edge (x, y) = (−50,0), and we’ll put the outlet/absorber in the middle of the right edge (x, y) = (+50,0). Again, the particle will diffuse around randomly between these points and when the absorbing point at (x, y) = (+50,0) is reached, the simulation ends. At each time step, the particle can move one step on the grid and your simulation will update the particle’s x and y positions accordingly. Here are the rules for the random walk:

At each time step:

1. If the particle is not at an edge, it can take a step of one grid spacing in any of four directions: ±x, ±y; these should all be equally probable.

2. If the particle is at one of the edges, but not at the absorber, it cannot pass out of the box. It should have a 50% probability of taking a step perpendicularly away from the wall, and a 25% chance of stepping in either of the directions along the wall.

3. If the particle is at a corner, it has a 50% chance of going in either of the two directions along the walls.

4. If the particle touches the absorbing point at (x, y) = (+50,0), the random walk ends.

Part 2. Simulate a single 2d random walk until absorption.

D. (20 pts) Write a program that executes one ‘walk’ and calculates the number of steps the particle takes before being absorbed – the residence time of our two-dimensional lake for that tracer. You will be assessed on whether you have correctly implemented the walking rules above.

E. (10 pts) Make a plot of the trajectory taken by the particle (positions in x,y).

a. Label the x and y axes appropriately, and give the plot a title

b. Indicate the starting position with a black asterisk and the end position with a red asterisk.

F. (5 pts) Print the time (i.e. number of steps) it took for the particle to be absorbed.
