The purpose of this assignment is to apply a waiting line model to a business service operation in order to recommend the most efficient use of time and resources. (This assignment has been adapted from Case Problem 2 in Chapter 15 of the textbook.) Use the information in the scenario provided to prepare a managerial report for Office Equipment, Inc. (OEI). Scenario Office Equipment, Inc. (OEI) leases automatic mailing machines to business customers in Fort Wayne, Indiana. The company built its success on a reputation of providing timely maintenance and repair service. Each OEI service contract states that a service technician will arrive at a customer’s business site within an average of 3 hours from the time that the customer notifies OEI of an equipment problem. Currently, OEI has 10 customers with service contracts. One service technician is responsible for handling all service calls. A statistical analysis of historical service records indicates that a customer requests a service call at an average rate of one call per 50 hours of operation. If the service technician is available when a customer calls for service, it takes the technician an average of 1 hour of travel time to reach the customer’s office and an average of 1.5 hours to complete the repair service. However, if the service technician is busy with another customer when a new customer calls for service, the technician completes the current service call and any other waiting service calls before responding to the new service call. In such cases, after the technician is free from all existing service commitments, the technician takes an average of 1 hour of travel time to reach the new customer’s office and an average of 1.5 hours to complete the repair service. The cost of the service technician is $80 per hour. The downtime cost (wait time and service time) for customers is $100 per hour. OEI is planning to expand its business. Within 1 year, OEI projects that it will have 20 customers, and within 2 years, OEI projects that it will have 30 customers. Although OEI is satisfied that one service technician can handle the 10 existing customers, management is concerned about the ability of one technician to meet the average 3-hour service call guarantee when the OEI customer base expands. In a recent planning meeting, the marketing manager made a proposal to add a second service technician when OEI reaches 20 customers and to add a third service technician when OEI reaches 30 customers. Before making a final decision, management would like an analysis of OEI service capabilities. OEI is particularly interested in meeting the average 3-hour waiting time guarantee at the lowest possible total cost. Managerial Report Develop a managerial report (1,000-1,250 words) summarizing your analysis of the OEI service capabilities. Make recommendations regarding the number of technicians to be used when OEI reaches 20 and then 30 customers, and justify your response. Include a discussion of the following issues in your report: 4. OEI is satisfied that one service technician can handle the 10 existing customers. Use a waiting line model to determine the following information: (a) probability that no customers are in the system, (b) average number of customers in the waiting line, (c) average number of customers in the system, (d) average time a customer waits until the service technician arrives, (e) average time a customer waits until the machine is back in operation, (f) probability that a customer will have to wait more than one hour for the service technician to arrive, and (g) the total cost per hour for the service operation. I need help with this part, please show all your work.

7.22 LAB*: Program: Online shopping cart (Part 2)

This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program).

(1) Extend the ItemToPurchase class per the following specifications:

• Parameterized constructor to assign item name, item description, item price, and item quantity (default values of 0). (1 pt)
• Public member functions
  • SetDescription() mutator & GetDescription() accessor (2 pts)
  • PrintItemCost() - Outputs the item name followed by the quantity, price, and subtotal
  • PrintItemDescription() - Outputs the item name and description
• Private data members
  • string itemDescription - Initialized in default constructor to "none"

Ex. of PrintItemCost() output:

Bottled Water 10 @ $1 = $10

Ex. of PrintItemDescription() output:

Bottled Water: Deer Park, 12 oz.

(2) Create three new files:

• ShoppingCart.h - Class declaration
• ShoppingCart.cpp - Class definition
• main.cpp - main() function (Note: main()'s functionality differs from the warm up)

Build the ShoppingCart class with the following specifications. Note: Some can be function stubs (empty functions) initially, to be completed in later steps.

• Default constructor
• Parameterized constructor which takes the customer name and date as parameters (1 pt)
• Private data members
  • string customerName - Initialized in default constructor to "none"
  • string currentDate - Initialized in default constructor to "January 1, 2016"
  • vector < ItemToPurchase > cartItems
• Public member functions

  • GetDate() accessor (1 pt)
  • AddItem()
    • Adds an item to cartItems vector. Has parameter ItemToPurchase. Does not return anything.
  • RemoveItem()
    • Removes item from cartItems vector. Has a string (an item's name) parameter. Does not return anything.
    • If item name cannot be found, output this message: Item not found in cart. Nothing removed.
  • ModifyItem()
    • Modifies an item's description, price, and/or quantity. Has parameter ItemToPurchase. Does not return anything.
    • If item can be found (by name) in cart, check if parameter has default values for description, price, and quantity. If not, modify item in cart.

Two species of rat were grown under controlled conditions for 16 days and the following weight gains (in grams) were obtained. If the number is negative, it means the rat lost weight. (calculate everything for this problem - do not use built in excel formulas)
Species A -23 4 0 -18 7 32 -4 -2 Species B 21 38 20 24 24 58 16 -16 14 28 -5 25

a) Calculate a 95% confidence interval for each species mean b) Calculate a 95% confidence interval for the difference of the means between each species c) Test the hypothesis that species A has gained no weight. d) Test the hypothesis that the means are equal for both species. (Solve it, do not use Excel formulas) e) Based on your results, describe the differences between the following methods for comparing the samples, and assess whether each is an effective method. Be specific in terms of what each method tells you about these two samples (not just what the results are, but what the method is actually examining to get those results). In other words, which methods, if any, can be misleading, and why? 1) Looking for overlap between the mean ± 1 standard deviation 2) Looking for overlap between (mean ± SE) 3) Looking for overlap between (mean ± 2SE) 4) Looking for overlap between the ranges 5) Seeing if the 95% confidence interval of the difference of the means includes 0.

In a Risk Behavior Survey study on college students the following variables were observed:

Risk Behavior Variable:  

Did not wear seatbelt while last time driving a car (0=Wear seatbelt, 1=Not wear seatbelt)

      Risk Factor Variables:

• Sex   (0=Female, 1=Male)
• Race   (1=White, 2=Black, 3=Other)
• Live on campus   (0=Off Campus, 1=On Campus)

The data is in the following address:    http://gchang.people.ysu.edu/stat/log-YRB-18f.xls

(Do not use stepwise regression.)

1. Report the raw odds ratios of not wearing seatbelt for

1. Male versus Female and,
2. White race versus Other race, and
3. Lived On Campus versus Off Campus.

2. Use multiple logistic regression (logistic regression using multiple explanatory variables) to find the significant factor(s) that affects whether students wearing seatbelt or not. (Use all risk factor variables to build the regression model. Do not drop any variables.)

[Paste the R logistic regression output containing parameter estimation information here!]

3. Report the adjusted odds ratios of not wearing seatbelt for

1. Male versus Female and,
2. White race versus Other race, and
3. Lived On Campus versus Off Campus.

(Use the model built in question 2 for answering this question. Do not drop any variables.)

The two companies below are simultaneously deciding to enter the same untapped retail market and opportunities look excellent. The only issue for each is the size of the store to be built. Expected payoffs in millions of dollars are below.

                                                Big-Box                                             

                                    Small       Medium      Large                                                                                                              

               Small :          16,30       8,20           10,10  

YMart:                                                          

               Medium :       18,18       12,15         14, 8

               large   :           15,25       10,23         16, 20             

As a simultaneous play game, (for parts A and B below)

(A) (4 pts) Which, if any, of the players has a dominant strategy?

                        ANSWER: ______________________

(B) (3 pts) If any Nash equilibria exist, identify them. If they are none, so state.

                        ANSWER: ____________________

(C) (3 pts) Now suppose instead of a simultaneous play game, Big-Box, because of better planning and foresight, had the advantage of going first and turning the competition into a sequential game, if it so chooses. However, to go first and credibly go first, Big-Box has to accelerate its construction plans. Because of union overtime provisions and other costs of acceleration, Big-Box would have additional costs of $1 million dollars if it announces and begins building. If it doesn’t choose to accelerate, it has no fear that Ymart will go first because Ymart’s acceleration costs are prohibitive of that strategy.

Should Big-Box go first? Why or why not? Clearly explain your reasoning.

Question 1: Write a program in C++ using multi filing which means 3 files ( main file, header file, and functions file) and attached screenshots as well. Attempt the Question completely which contain a and b parts

a) Write a program that takes a number from the user and checks whether the number entered validates the given format: “0322-5441576”, xxxx-xxxxxxx where “x” implies the digits only and first two digits are 0 and 3 respectively. The program also identifies the Network of the given number. (Use of string related functions is a must)

b) Write a program that takes a string from the user, identifies and counts all unique characters in that given string. You are bound to use only built-in string functions where necessary. For identification of unique characters and for counting of the characters make separate functions.

For character identification

Develop a program that takes a string argument, and returns an array containing all unique characters.

For character counting

Develop a program that takes an array returned from above function as an argument along with the given string and return an array containing the total count of each uniquely identified character present in the argument array.

Note: kindly write a proper code of program mention in Question and answer complete Question along with both parts and screenshots Thanks.....
