1. A small mattress company recently started its operations and currently does not have enough resources to utilize high-tech forecasting software. The manager wants to utilize traditional methods of forecasting to estimate demand. The following recent data on monthly sales are available from the past year. Use this information to answer the following set of questions.

1. If the manager uses a naïve forecasting method. What is the forecast for Jan 2020? (2 pts.)

1. Use the three-period moving average method and estimate forecast beginning from Aug-19 to Jan-20. Use 0.4, 0.3, and 0.2 as weights with highest weights given to the most recent periods (8 pts.)
   
2. Calculate the Mean Absolute Deviation of forecasts from the three-period moving average. (5 pts.)
   

              2. Use the same date from Q1. to answer the following questions. (10 pts.)

1. Use the exponential smoothing method to calculate forecast from Aug-19 to Jan-20. Use an α value of 0.3.

You need a beginning forecast of Jul-19 to start this. Use the naïve forecast for estimating Jul-19, and then use the answer to start the exponential smoothing method.

An industrial engineer at an appliance repair company compared a new strategy for dispatching its service technicians to its usual way. The new strategy consisted of using software to solve the vehicle routing problem (a mathematical program) each morning after several service calls came in. The old way was to simply wait for a service request, then send any available technician. Each of the thirty-six technicians was assigned to either the old or new way, so that there were exactly eighteen in each group. The company carried out this experiment over 40 working days, and the average daily mileages for the thirty-six repairpersons are below.

a) Make boxplots, probability plots, and run Anderson-Darling and Shapiro-Wilks tests to check for normality. Is the normality assumptions in question Explain.
b) If you think the normality assumptions are violated, you need to run some other kind of test, like a nonparametric test. One reasonable choice would be the Mann-WhitneyWilcoxon rank sum test. Use R to run this test. Provide your code, output, and remarks in your solutions.

An isotonic solution will produce an osmotic pressure of 7.84 atm measured against pure water at human body temperature (37.0 °C). How many g of sodium chloride must be dissolved in a liter of water to produce an isotonic solution?

9. The American novelist James Baldwin wrote, "Words like freedom, justice, democracy are not common concepts; on the contrary, they are rare. People are not born knowing what these are. It takes enormous and, above all, individual effort to arrive at the respect for other people that these words imply." Ask students to define the terms freedom, justice, and democracy. How did the students derive their own meaning for these words?

Write a complete C++ program to implements a Min-heap.

Each node will contain a single integer data element. Initialize the Min-heap to contain 5 nodes, with the values 8, 12, 24, 32, 42.

The program should allow for the insertion and deletion of nodes while maintaining a Min-Heap.

The program should allow the user to output data in Preorder, Inorder and Postorder.

The program should loop with menu items for each of the above objectives and the choice to quit

Here's the code:

C++

For this assignment, you will implement the MyString class. Like the string class in C++’s standard library, this class uses C-strings as the underlying data structure. Recall that a C-string is a null-terminated array of type char. See section 8.1 in Savitch for more information about C-strings; in particular, you will find it helpful to take advantage of several of the C-string functions mentioned in that section. What To Do. In the hw8 directory that is created, you will find the following files: • mystring.h and mystring.cpp • a Makefile • and 4 test files (test1.cpp through test4.cpp). (Below are the files mentioned here, with one sample file). Implement the following: 1. a default constructor 2. a constructor that takes a const char * parameter (that is, a C-string) 3. a destructor 4. a copy constructor 5. the assignment operator. In addition, overload the following relational operators: >, <, >=, <=, ==, and !=. Lastly, overload the operator+ (concatenation). All of the relational operators return type int. To understand why, read the description of the C-string function strcmp. All of the comparisons should be lexicographical, i.e., similar to what strcmp() does. The == and != operators should evaluate to 1 if the condition is true, 0 if false. You are welcome to implement some of the operators by using others (for example, you can easily implement != using ==). Make sure that you can invoke the operators with string literals on either side of the operator. That is, both of the following expressions should be valid: str == "hello" "hello" == str where str is a MyString object. Place the member function implementations in mystring.cpp and compile using make. You can also edit mystring.h if you wish to implement some of the member functions directly in the class definition

Explain two factors that may affect the IT project cost estimation using your own words. Support your answer with examples.

True/False: The advantage to being the late mover or follower strategy is that you learn from the mistakes that the first mover makes.

True/False: Firms have to choose between two different strategies of entry one is a non-equity strategy and the other is an equity strategy.

True/False:Joint ventures are considered a desirable strategy for firms that want tight control over the foreign operations.

Please also give a reasoning if you can, thanks!

The Neal Company wants to estimate next year's return on equity (ROE) under different financial leverage ratios. Neal's total capital is $14 million, it currently uses only common equity, it has no future plans to use preferred stock in its capital structure, and its federal-plus-state tax rate is 40%. The CFO has estimated next year's EBIT for three possible states of the world: $5.8 million with a 0.2 probability, $3.4 million with a 0.5 probability, and $0.6 million with a 0.3 probability. Calculate Neal's expected ROE, standard deviation, and coefficient of variation for each of the following debt-to-capital ratios. Do not round intermediate calculations. Round your answers to two decimal places at the end of the calculations.

Debt/Capital ratio is 0.

Debt/Capital ratio is 10%, interest rate is 9%.

Debt/Capital ratio is 50%, interest rate is 11%.

Debt/Capital ratio is 60%, interest rate is 14%.
