3. Collected $166,400 from accounts receivable.
4. Paid $129,000 cash for operating expenses.
5. Adjusted the accounts to recognize uncollectible accounts expense. Jova uses the allowance method of accounting for uncollectible accounts and estimates that uncollectible accounts expense will be 2 percent of sales on account.

The following transactions apply to Jova for Year 2:

Assume that you recently graduated and you just landed a job as a financial planner with the Cleveland Clinic. Your first assignment is to invest $100,000. Because the funds are to be invested at the end of one year, you have been instructed to plan for a one-year holding period. Further, your boss has restricted you to the following investment alternatives, shown with their probabilities and associated outcomes.

Barney Smith Investment Advisors recently issued estimates for the state of the economy and the rate of return on each state of the economy. Alta Industries, Inc. is an electronics firm; Repo Men Inc. collects past due debts; and American Foam manufactures mattresses and various other foam products. Barney Smith also maintains an "index fund" which owns a market-weighted fraction of all publicly traded stocks; you can invest in that fund and thus obtain average stock market results. Given the situation as described, answer the following questions using Excel (Please Show Excel Formulas).   

a. Calculate the expected rate of return on each alternative.

b. Calculate the standard deviation of returns on each alternative.                                               

c. Calculate the coefficient of variation on each alternative.                        

d. Calculate the beta on each alternative.                                                                                            

e. Do the SD, CV, and beta produce the same risk ranking? Why or why not?

Smoky Mountain Corporation makes two types of hiking boots—the Xtreme and the Pathfinder. Data concerning these two product lines appear below:

The company has a traditional costing system in which manufacturing overhead is applied to units based on direct labor-hours. Data concerning manufacturing overhead and direct labor-hours for the upcoming year appear below:

Required:

1. Compute the product margins for the Xtreme and the Pathfinder products under the company’s traditional costing system.

2. The company is considering replacing its traditional costing system with an activity-based costing system that would assign its manufacturing overhead to the following four activity cost pools (the Other cost pool includes organization-sustaining costs and idle capacity costs):

Compute the product margins for the Xtreme and the Pathfinder products under the activity-based costing system.

3. Prepare a quantitative comparison of the traditional and activity-based cost assignments.

A 78-year-old female was arrived tired to the emergency room with the following symptoms: nausea, vomiting, decreased respiration, hypotension, and low pulse rate (46), The skin was not sweaty, it was warm, she is DM, swelling, she take some medication like metfromin 850mg, some diuretics, The patient had been treated for constipation and heartburn (antacids) within the last 24 hours.

Laboratory investigation resulted in the following:

1. What explanation would you give the doctor for the difference in the electrolytes levels?

2. What is the most likely cause for the hypermagnesemia?

3. Which type of diabetes mellitus should be considered? And why?

type 2 diabetes.

4. What is your explanation for kidney function tests result (high Creatinine and BUN)? Is it indication for pyelonephritis or GFR dysfunction or acute kidney failure? Justify your answer.

5. Does the patient suffer from microalbuminuria regarding to albumin result? Justify your answer.

Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups.

1.     Paste the relevant SPSS output. (2 pt)

2.     Create an appropriate graph to display this data (make sure you have labels on both x and y axes). (2 pts)

3.        Write an APA-style Results section based on your analysis. All homework “Results sections” should follow the examples provided in the presentations and textbooks. They should include the statistical statement within a complete sentence that mentions the type of test conducted, whether the test was significant, and if relevant, effect size and/or post hoc analyses. Don’t forget to include a decision about the null hypothesis. (3 pts)

The Yoran Yacht Company (YYC), a prominent sailboat builder in Newport, may design a new 30-foot sailboat based on the "winged" keels first introduced on the 12-meter yachts that raced for the America's Cup.

First, YYC would have to invest $14,000 at t = 0 for the design and model tank testing of the new boat. YYC's managers believe there is a 60% probability that this phase will be successful and the project will continue. If Stage 1 is not successful, the project will be abandoned with zero salvage value.

The next stage, if undertaken, would consist of making the molds and producing two prototype boats. This would cost $500,000 at t = 1. If the boats test well, YYC would go into production. If they do not, the molds and prototypes could be sold for $100,000. The managers estimate that the probability is 80% that the boats will pass testing and that Stage 3 will be undertaken.

Stage 3 consists of converting an unused production line to produce the new design. This would cost $1 million at t = 2. If the economy is strong at this point, the net value of sales would be $3 million; if the economy is weak, the net value would be $1.5 million. Both net values occur at t = 3, and each state of the economy has a probability of 0.5. YYC's corporate cost of capital is 11%.

1. Assume this project has average risk. Construct a decision tree and determine the project's expected NPV. Do not round intermediate calculations. Round your answer to the nearest cent.

2. Find the project's standard deviation of NPV and coefficient of variation (CV) of NPV. Do not round intermediate calculations. Round the project's standard deviation to the nearest cent and CV to two decimal places.

Let x be the number of different research programs, and let y be the mean number of patents per program. As in any business, a company can spread itself too thin. For example, too many research programs might lead to a decline in overall research productivity. The following data are for a collection of pharmaceutical companies and their research programs.

Complete parts (a) through (e), given Σx = 90, Σy = 8, Σx² = 1420, Σy² = 11.58, Σxy = 112.6, and

r ≈ −0.925.

(a) Draw a scatter diagram displaying the data.

(b) Verify the given sums Σx, Σy, Σx², Σy², Σxy, and the value of the sample correlation coefficient r. (Round your value for r to three decimal places.)

(c) Find x, and y. Then find the equation of the least-squares line  = a + bx. (Round your answers for x and y to two decimal places. Round your answers for a and b to three decimal places.)

(d) Graph the least-squares line. Be sure to plot the point (x, y) as a point on the line.

(e) Find the value of the coefficient of determination r². What percentage of the variation in y can be explained by the corresponding variation in x and the least-squares line? What percentage is unexplained? (Round your answer for r² to three decimal places. Round your answers for the percentages to one decimal place.)

(f) Suppose a pharmaceutical company has 13 different research programs. What does the least-squares equation forecast for y = mean number of patents per program? (Round your answer to two decimal places.)
