You are constructing a portfolio of two assets, Asset A and Asset B. The expected returns of the assets are 12 percent and 16 percent, respectively. The standard deviations of the assets are 36 percent and 44 percent, respectively. The correlation between the two assets is 0.55 and the risk-free rate is 5.1 percent. What is the optimal Sharpe ratio in a portfolio of the two assets? What is the smallest expected loss for this portfolio over the coming year with a probability of 16 percent? (A negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your Sharpe ratio answer to 4 decimal places and the z-score value to 3 decimal places when calculating your answer. Enter your smallest expected loss as a percent rounded to 2 decimal places.)

Report from day shift nurse:

Situation: Christopher Parrish is an 18-year-old male who was admitted at 1900 today. His mother visited him at his college dormitory and was very concerned with his health; he seemed weak and had lost weight since she last saw him. She took him to see his primary care provider, and the provider admitted him and has ordered a tube feeding. I placed an 8-Fr, 42-inch feeding tube in his right nares about an hour ago. The pump is in his room. He is up to the bathroom prn; otherwise bed rest.

Background: Christopher was diagnosed with cystic fibrosis as a child and has had frequent hospitalizations previously. He reports fatigue and has recently lost 6 kg (13.2 lb) after he registered at the local college and moved to live in a dormitory. Chris's mom was here earlier, but she is a single parent and has two younger boys, so she had to go home.

Assessment: Christopher is awake and alert. His heart rate and rhythm are regular at 80–85/min. Breath sounds are fine with a respiratory rate at 18/min. His color is a bit pale. Blood pressure is 118/78 mm Hg. He reports no pain and states he's not had much appetite the past few weeks. His belly is flat and nontender. Bowel sounds are normoactive.

Recommendation: Christopher is due for vital signs and assessment. The tube feeding just arrived, and you will need to start it on the pump. He needs 720 kilocalories over 8 hours overnight. His regular diet is high calorie, high fat, but he wasn't too hungry this evening; just had a bit of his chocolate shake. You will need to give his pancreatic enzymes orally before you start the tube feeding. You should also assess his diet and reinforce patient education on nutrition.

You just placed a feeding tube into the right nare of the patient. What is something you would do or suggest the MD order before starting the tube feedings?.

You have been ordered to reinforce patient education. Why is nutrition education important for this patient?

What lab(s) might the MD order to evaluate a patent's nutritional status?

Irene and Orville live in an isolated valley and trade with no one but each other. They consume only cantaloupes and grapefruits. Irene has an initial endowment of 12 cantaloupes and 19 grapefruits. Orville has an initial endowment of 8 cantaloupes and 14 grapefruits. For Irene, the two goods are perfect substitutes, one for one. For Orville, they are perfect complements, one for one. At all Pareto efficient allocations, Select one: a. Irene must consume at least 13 cantaloupes. b. The slopes of the two individuals’ indifference curves are the same c. Orville must consume all of the cantaloupes. d. Irene must consume at least 17 grapefruits. e. None of the answers is correct. f. Irene must consume at least 13 grapefruits. g. Orville must consume all of the grapefruits.

An element crystallizes into a structure which may be described by a cubic type of unit cell 7. having one atom in each corner of the cube and two atoms on one of its face diagonals. If the volume of this unit cell is 24 x 10-24 cm3 and density of the element is 7.20 gm/cm3, calculate number of atoms present in 200 gm of the element

question 20

Three identical units of merchandise were purchased during July, as follows:

Assume one unit sells on July 28 for $34.

Determine the gross profit, cost of goods sold, and ending inventory on July 31 using (a) first-in, first-out, (b) last-in, first-out, and (c) average cost flow methods.

Directions: Conduct a T test for Dependent Samples to answer the questions based on the following scenario. (Assume a nondirectional research hypothesis ( two-tailed test) and a level of significance of .05)

To further examine the school performance scores of the district the superintendent identified schools within the district that could be matched to schools from surrounding districts using a series of demographic characteristics such as size, socio-economic status, and percent special education students. The data that were collected are presented above.

1. What are the mean school performance scores for the superintendent's district and matched schools?

2. What are the standard deviations of the school performance scores for the superintendent's district and matched schools?

3. State an appropriate null hypothesis for the analysis.

4. What is the observed or computed value of t?

5. What is the value of degrees of freedom that are reported in the output?

6. What is the reported level of significance from the T Test for Dependent Means?

7. Based on the result of the T Test for Dependent Means, what would you conclude about the difference in scores of schools in the superintendent's district and the matched schools?

8. Present the result as they might appear in an article. This must include a table and narrative statement that reports the results of the T Test for Dependent Means.
