Mountain Company manufactures Hiking shoes and walking shoes. The projected incomefrom the two products is: Hiking shoes Walking shoes Sales $ 900,000 $1,500,000 Less: Variable costs (540,000) (600,000) Contribution margin 360,000 900,000 Less: Direct fixed expenses (400,000) (440,000) 2 Segment margin (40,000) 460,000 Less: Common fixed costs (allocated) (100,000) (150,000) Net income (loss) $ (140,000) $ 310,000 After studying the latest market evaluates, project manager is considering recommending that the president drop the Hiking shoe line. If the line is dropped, however, the saleof walking shoes will drop by 5%. In addition, there is a personal complication for the project manager. Mountain is locatedin a rural area where unemployment is over 12%. If the Hiking shoe division is shutdown, there will be layoffs, including the manager of the division. Manager of the division and project manager have been friends since high school. Their families get together atleast once a month. Manager of the division's wife is principal of the local elementary school,a job she loves. Required a. Explain a project manager's ethical obligations in this matter b. Should Mountain keep or drop the Hiking shoe line? Support your answer with appropriate calculations c. Marketing department has come back to the project manager with an analysisthat shows if advertising were increased by $50,000, then Hiking shoes sales would go up by5% and walking shoes by 3%. Should advertising be increased? Again, prove withyour supporting calculations d. If the Hiking shoe line is shut down, Mountain will have excess capacity. In carrying out her analyses, the project manager has been able to come up with only one viable alternative. The company could use part of the capacity to make canvas slippers.Estimated sales revenue from the slippers would be $300,000, and variable costs would be$170,000. Direct fixed expenses would be reduced to $100,000, and allocated fixed expenses wouldbe $50,000. While this option would not use all the available capacity, it would reduce the number of layoffs. Should the project manager recommend that this option be carried out?

Part 1 – Calculate and use descriptive statistics to compare hourly wages for each of the education levels. Be sure to include the mean, standard deviation and margin of error with 95% confidence for each of the 3 levels (9 calculations). These calculations range in value from 3-4 points each for a total of 33 points. Note: See page 293 for the margin of error formula.

Part 2 – Construct and interpret 95% confidence intervals for the mean hourly wage at each education level. There should be an upper and lower number for each of the 3 levels. The end result should be 6 numbers which are valued at 3 points each for a total of 18 points.

You are expected to use Excel functions for the majority of your calculations. 10 points are allocated to the use of Excel. I will check within the cells to find/confirm your formulas and summation. An additional 10 points are allocated to showing your work (calculations). If you use Excel you receive the combined amount (20 points). If you perform the calculations by hand and show your work on paper you will receive only 10 points. Use Excel! It is a great tool that will serve you well in your future endeavors. The case study is valued at a total of 100 points.

    You are on duty in the OPD when BV is a 7-year old schooler who went for doctor’s consult because of severely swollen tonsils. She was accompanied by her mother. Condition started 3 days prior to consult, becoming more progressive until she can hardly swallow. She also started having low grade fever the day before but became high grade in the morning of consult. Her mother said this problem is frequently occurring since she started going to school like almost every 3 to 4 months. She usually does not miss school unless she has fever like what happened the past days.

            Upon assessment, BV is a little bit restless and occasionally grimaces when she swallows. She remarks that mere swallowing of her saliva gives her pain. Though all aspects of her vital signs are bordering on maximum normal, her temperature registered at 39.4 C. Inspection of her throat shows erythema with exudates on both lateral walls.

            After completing history and assessment, the doctor did a throat swab then gave instructions on the following orders:

           Cephalexin (Keflex) 500 mg every 6 hours for 7 days.

           Betadine gargle 3 times a day.

           Paracetamol 500 mg every 6 hours for temperature 38.5 C and above

          They were told to come back after a week for follow-up. The doctor mentioned the need for referral to a throat specialist for a possible scheduling of her surgery. Upon hearing this, BV verbalized her concern to her mother about a coming Quiz Bee Contest where she is a contestant and her possible absence if she will undergo surgery. She is now more apprehensive than when she came in.

Questions

1. Give 5 nursing diagnoses applicable to BV based on her condition and stage of development and suggest applicable 3 nursing interventions for each diagnosis to address these problems. Risk problems may be included

35-43. A room of researchers are debating what variables predict attitudes towards scientists.

Researcher 1 says, "In a comparison of individuals, older people will rate scientists higher than younger people."

Researcher 2 says, "In a comparison of individuals, those with higher education will rate scientists higher than those with less education."

The following is a real regression model created using the 2016 ANES. The dependent variable, feelings towards scientists, ranges from 0-100. Party ID is coded 0=Democrat, 1=Independent, 2=Republican. Female is a dummy variable, coded 0=male and 1=female. Education is coded 0=high school or less, 1=some college, 2=college degree, and 3=graduate degree. Age is coded 0=18-29, 1=30-49, 2=50-64, 3=65+.

35. What does the coefficient for age mean? (Explain in one sentence)

36-37. Is Researcher 1's hypothesis right? How do you know? (note: to get the point, you must explain your answer.)

38. What does the coefficient for education mean? (Explain in one sentence)

39-40. Is Researcher 2's hypothesis right? How do you know?

41. What would be the predicted rating of scientists for an 25 year old, high school educated, Democrat male? Show your work.

42. What would be the predicted rating of scientists for an 25 year old, college educated, Republican male? Show your work.

Alameen is a railway system and wants to install Ticket Vending Machines (TVMs) on the platforms of all rail stations in Peshawar. The TVMs will allow the passenger to buy a ticket/pass using cash, coins, debit cards, or credit cards. The interface of the TVMs should be very easy for the passengers to buy their tickets.

This system should be designed in such a way that the passenger first selects the ticket type, transaction mode, and then get a pass/ticket. Passengers can be adult, senior/disabled citizens, child (5-14 years old), high school, or college students. Ticket type can be either a two-hour pass, midday pass, or AM pass (Monday through Friday from 09:30 am to 02:30 pm), a PM pass (noon through the end of service on the date purchased), a day pass, a 7-day pass, or a 31-day pass. There will be no ticket fare for senior or disabled citizens. The only thing they have to show during traveling is the valid ID and ticket. The ticket fare for a child (5-14 years old), high school or college students will be reduced, and they will have to show valid Id along with ticket (reduced fare) to the ticket checking authority.     

The system should restrict the unauthorized users from using the system. The system should be fast enough that it should accept the input from the user in less than 1 second. The system should be fast enough to print the ticket to the user within 3 to 5 secs when user inserts all the required information. The system should be available 24 hours a day and 7 days a week. The system will also be used by the operator to know the cash and coins inside the machine and withdraw or deposit cash when required. The system is designed in such a way to allow admin to generate reports. The reports include how many tickets are sold, the number of transactions, cash or coins collected, change fares, cash, or coins dispensed.
