In using statistical test of hypothesis in general and in business in particular, business practitioners face two types of errors: type I and type II error. Discuss each type of error in detail. In your opinion which type has more severe consequences in business? Support your opinion by providing an example. Also, discuss what is P-Value and its connection to type I error.

In this week’s lab you will look for examples of phenotypic variation within and between species of plants, using both your unassisted eye and a microscope. But what sorts of phenotypeswill you not be able to observe in lab, and might they be variable, too? In your answer, detail two other kinds of unobservable (with our methods) phenotype that might vary within and between species and give a concrete example of each.

You are the manager of Coca-Cola and are facing the effect of a research (published in 2004) that reports that consuming high fructose corn syrup (HFCS) is associated with promoting obesity. Consider the number of news reports and the number of other research papers on this topic that have been published since 2004. This issue is relevant to you because HFCS is the sweetener used in soft drink manufacturing. Then, you are to:
1.1 Define the own price elasticity of demand.
1.2 Write out a nonlinear demand equation for Coca-Cola that includes the appropriate demand shifters. Based on economic theory, attach the appropriate sign to the coefficient on each right hand side variable.
1.3 Given the number of news reports and other research papers that focus on the positive relation between HFCS and obesity, explain how this is represented by the demand equation for Coca-Cola.
1.4 Use economic theory to explain the meaning of the coefficient on each explanatory variable.
1.5 What would you do to offset the effect of the HFCS-obesity research on the demand for Coca-Cola? Based on economic theory explain your decision. Explain if your decision is working.
1.6 Would you increase or decrease price to boost Coke sales? Based on economic theory, explain your choice.
1.7 Based on economic theory, explain how Coke’s advertising would affect the demand for Pepsi.
1.8 Based on economic theory, explain why you would spend a lot of money on.
1.9 What is the effect of population on consumption of Coca-Cola?
1.10 Assume that consumers are worried about the positive relation between consumption of HFCS and obesity, so consumers may increase bottled water consumption. Explain the effect of this on the demand for Coca-Cola. Is the cross price elasticity of demand between Coca-Cola and bottled water negative of positive, explain?

This issue is relevant to you because HFCS is the sweetener used in soft drink manufacturing. Then, you are to:
1. Define the own price elasticity of demand.
2. Write out a log-linear demand equation for Coca-Cola that includes the appropriate demand shifters. Based on economic theory, attach the appropriate sign to the coefficient on each right hand side variable.

In the video, studies of twins were used to add evidence to a debate about whether an individual's character is formed primarily from their genetics or their environment. Review your course readings and answer the following questions related to the Nature or Nurture debate
In your own words, explain how the use of twin studies can help to clarify whether characteristics are determined primarily by genes or environment.
The assumption made in this debate is that factors in an individual’s genetic make-up, or in their environment, cause how they act as adults. Discuss whether you agree with that assumption and why or why not.
In your opinion, does the high degree of correlation between the behavior of twins prove that genetics causes their behavior?
Why might you question how well one variable predicts another, such as whether genes or environment predicts adult behavior?
Thinking about your own life experiences, describe reasons why your genetics or childhood environment might fail to predict your current decisions and actions.

M&M'S MILK CHOCOLATE: 24% cyan blue, 20% orange, 16% green, 14% bright yellow, 13% red, 13% brown.
Each large production batch is blended to those ratios and mixed thoroughly. However, since the individual packages are filled by weight on high-speed equipment, and not by count, it is possible to have an unusual color distribution.
1. Treat your bag of M&M's as a simple random sample and:
a. Count the following --
Number of GREEN M&M's: 9
Total number of M&M's: 56
Proportion of GREEN M&M's: 9/56
b. See if the requirements for constructing a confidence interval for proportions are satisfied. Show your work here:
c. The conditions might not be satisfied, depending on how many candies were in your bag. If the conditions are not met, what could you do? (note—you don’t have to do it, just say what you would do)
d. Construct a 95% confidence interval for the proportion of GREEN M&M's using your data (not using any classmate data yet). Feel free to use the calculator’s Interval command. Be sure to include an interpretation of your interval.
My interval:

A red ball is thrown down with an initial speed of 1.3 m/s from a height of 27 meters above the ground. Then, 0.5 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 24 m/s, from a height of 0.8 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s2
What is the speed of the red ball right before it hits the ground?
(Is it just jus the velocity equestion?)
How long after the red ball is thrown are the two balls in the air at the same height?
Maybe I am not doing something right, but this is what I have:
27 - 1.3t - 4.9t^2 = -4.9t^2 + 28.9t-12.425
with -4.9t^2 + 28.9t-12.425 being derived from .8 +
24(t-.5)-4.9(t-.5)^2 the only thing I can thing of would be to
maybe to have it as 8 + 24(t+.5)-4.9(t+.5)^2 ?
Is the acceleration postive or negative and is speeding up or slowing down?

You are a software development employee at a startup company. Your HR department has tasked the IT department with developing a simple application (Windows Form Application) to load and display employee records.
Your application will need to do the following:
Create an Employee Class with the following properties:
First Name
Last Name
Street Address
City
State
Zip
Create a sub class for Managers which inherits from the Employee Class. The Manager class will have the following additional properties:
Cost Center
Supervisor
Create a sub class for Developers which inherits from the Employee Class. The Developer class will have the following additional properties:
Developer Type (Script, .NET, Mobile, etc.)
Supervisor
Tax Type (W2, 1099-Contract)
Load employee information from a text file selected by the user into an array consisting of Managers and Developers. The format of your text file should be something like this:
First Name, Last Name, Street Address, City, State, Zip, Employee Type (Manager or Developer), Cost Center (0 if Developer), Supervisor, Tax Type (NA if Manager)
There should be a separate line for each employee (only one line per employee with the fields above) and your file should contain at least 7 - 10 employee records. You should save the file with a .txt or .csv extension.
The UI should allow the user to select how many records to view (start at 3 and allow up to the total number of records loaded).
The following requirements detail the critical elements that will determine the grading criteria for your submission. Please see the rubric below these requirements.
The application should compile and run successfully
The application should display Inheritance (Steps 1 - 3 above).
The application should allow the user to load a text or csv file for processing (Step 4 above).
The application should load the text file elements into an array of employee records (Step 4 & 4a above).
The application should display records from the array. The number of records to display should be selected by the user. (Step 5 above).
Your application should contain comments to explain the data and process flow of your code.
