1. A research study was conducted to examine the clinical efficacy of a new antidepressant. Depressed patients were randomly assigned to one of three groups: a placebo group, a group that received a moderate dose of the drug, and a group that received a high dose of the drug. After four weeks of treatment, the patients completed the Beck Depression Inventory. The higher the score, the more depressed the patient. The data are presented below. Use the Microsoft Excel "Anova Single-Factor" Data Analysis tool to conduct a 1-way ANOVA test for the data in the following table:
| Placebo | Moderate Dose | High Dose |
| 42 | 22 | 10 |
| 52 | 19 | 14 |
| 39 | 8 | 12 |
| 33 | 23 | 19 |
| 41 | 31 | 10 |

In this hypothetical case study, a new rapid test kit nicknamed Alpha is being reviewed. The sensitivity of Alpha is 93.0% (0.93) and the specificity is 96.0% (0.96). Assume that the actual prevalence of the Zika antibody among the United States population of blood donors is 4% (0.04) and that of the hurricane disaster relief volunteers returning from Puerto Rico is 20.0% (0.20).
Construct a separate 2 x 2 table, to calculate the PPV and NPV for a population of 2,500 volunteers who aided in the recent hurricane relief efforts in the Caribbean.
If sensitivity and specificity remain constant, what is the relationship of prevalence to predictive-value positive and predictive-value negative? (Hint: Think if one increases, decreases, or stays the same.)

Consider the TV shows you watched as kids. What was the gender of the characters? What did each character do? What role did the characters have in the show? Were there more male or female characters? How prominent are female roles? Are female characters positive or negative? Are there differences among the various types of shows you watched? What messages do these shows send to girls and to boys?

King City Specialty Bikes (KCSB) produces high-end bicycles. Costs to manufacture and market the bicycles at last year's volume level of 2,050 bicycles per month are shown in the following table:
| Variable manufacturing per unit | $226.00 |
| Total fixed manufacturing | $266,500 |
| Variable nonmanufacturing per unit | $54.00 |
| Total fixed nonmanufacturing | $282,900 |
KCSB expects to produce and sell 2,250 bicycles per month in the coming year. The bicycles sell for $610 each.
KCSB receives a proposal from an outside contractor who, for $160 per bicycle, will assemble 900 bicycles per month and ship them directly to KCSB's customers as orders are received from KCSB's sales force. KCSB would provide the materials for each bicycle, but the outside contractor would assemble, box, and ship the bicycles. The variable manufacturing costs would be reduced by 45% for the 900 bicycles assembled by the outside contractor, and variable nonmanufacturing costs for the 900 bicycles would be cut by 60%.
KCSB's marketing manager thinks that it could sell 75 specialty racing bicycles per month for $6,000 each, and its production manager thinks that it could use the idle resources to produce each of these bicycles for variable manufacturing costs of $4,900 per bicycle and variable nonmanufacturing costs of $450 per bicycle.
If KCSB accepts the proposal, it would be able to save $26,650 of fixed manufacturing costs; fixed nonmanufacturing costs would be unchanged.
REQUIRED [Note: Round unit cost computations to the nearest cent]
What is the difference in KCSB's monthly costs between accepting the proposal and rejecting the proposal? (Note: If the costs of accepting the proposal are less than the costs of rejecting it, enter the difference as a positive number; if the accept costs are more than the reject costs, enter the difference as a negative number.)

Although an insurance adjuster is highly skilled and experienced she sometimes lacks confidence in her abilities, particularly on new assignments. She seems to believe that any new accomplishments are due more to luck than her own expertise. Moreover, her work involves interacting with clients who are sometimes aggressive or hostile. This is a stressful situation to most insurance adjusters, including this employee.
Use path-goal theory to identify and describe the best leadership style or styles that this employee's immediate supervisor should use to improve her effectiveness as an insurance adjuster. Explain why this/these style(s) is/are appropriate in this situation.

AverageGrade. Assume the professor gives five exams during the semester with grades 0 through 100 and drops one of the exams with the lowest grade. Write a program to find the average of the remaining four grades. The program should use a class named Exams that has
1. An instance variable to hold a list of five grades,
2. A method that calculate and return average.
3. A string that return the “exams Average” for printing.
Your program output should prompt for an input for each grade. Use any number between 0 and 100. Your submission should include compiled output.

3. Neuroscience researchers examined the impact of environment on rat development. Rats were randomly assigned to be raised in one of the four following test conditions: Impoverished (wire mesh cage - housed alone), standard (cage with other rats), enriched (cage with other rats and toys), super enriched (cage with rats and toys changes on a periodic basis). After two months, the rats were tested on a variety of learning measures (including the number of trials to learn a maze to a three perfect trial criteria), and several neurological measure (overall cortical weight, degree of dendritic branching, etc.). The data for the maze task is below. Use the Microsoft Excel "Anova Single-Factor" Data Analysis tool to conduct a 1-way ANOVA test for the data in the following table:
| Impoverished | Standard | Enriched | Super Enriched |
| 22 | 17 | 12 | 8 |
| 19 | 21 | 14 | 7 |
| 15 | 15 | 11 | 10 |
| 24 | 12 | 9 | 9 |

Case Management Action Planning Case Study (250 words)
A case manager, Marie, is meeting with Michael Cornell, an individual in need of services, and his granddaughter Jennifer. Michael age 86, took a bad fall six weeks ago and has been receiving rehabilitation services at a local nursing facility. Discharge planning was not thorough as Michael insisted he was ready to go home with services in place or not. Jennifer is not able to provide Michael with all the assistance he needs, but is willing to help as much as she can. However, it has become apparent to both Michael and Jennifer that he will not be able to remain at home without assistance. As a result of the fall, Michael had a hip replacement and a broken arm which was put in a cast. He also has diabetes, (two toes amputated in the last two years), and macular degeneration. Michael has become quite confused since his stay at the nursing facility and currently his decision making skills are severely impaired. He needs extensive assistance with dressing, bathing, toileting and transfers. Michael is not eating well and continues to lose weight. Michael tells Jennifer and Marie that he has no energy, feels down a lot and doesnt even care about tending to his garden this year. He previously enjoyed socializing with people and hobbies like woodworking, gardening and painting, but they dont interest him much now. Michael attended the local Congregational Church, but has not been to church services since his fall. He agrees that it might be helpful to talk with the pastor, have people around during the day and is willing to accept services that will help him to be able stay at home. Michael and Jennifer are interested in agency directed services at this time and clearly want to receive case management services. Michael, Jennifer and Marie are now developing Michaels Action Plan together.
Some simple questions to start:
List all the potential issues regarding Michaels needs
What goals do you think Michael might have?
List all the possible services Michael would need
For each goal (based on the issues), write a plan including strategies and timeframes
Remember to:
Address the following in the plan:
The processes involved in addressing the clients needs
Recommendations regarding services, supports and referrals
Details of (potential) meetings conducted with the relevant professionals
Continuous improvement strategies
Support from the literature

From an Australian perceptive, how would you brief your staff who is going to be communicating with Japan, Thailand and Singapore, what would you put into an information session for your staff regarding the information needed to know about how to communicate with someone from Japan, Thailand and Singapore? Taking into consideration their culture and custom.
