MA260 Statistical Analysis I

Directions: Be sure to save an electronic copy of your answer before submitting it to Ashworth College for grading. Unless otherwise stated, answer in complete sentences, and be sure to use correct English, spelling, and grammar. Refer to the “Assignment Format” page located on the Course Home page for specific format requirements.

 

NOTE: Show your work in the problems.

 

1.   Compute the mean and variance of the following discrete probability distribution.

 

 

2.   The Computer Systems Department has eight faculty, six of whom are tenured. Dr. Vonder, the chair, wants to establish a committee of three department faculty members to review the curriculum. If she selects the committee at random:

 

a.   What is the probability all members of the committee are tenured?

 

b.   What is the probability that at least one member is not tenured? (Hint: For this question, use the complement rule).

 

3.   New Process, Inc., a large mail order supplier of women’s fashions, advertises same day service on every order. Recently, the movement of orders has not gone as planned, and there were a large number of complaints. Bud Owens, director of customer service, has completely redone the method of order handling. The goal is to have fewer than five unfilled orders on hand at the end of 95% of the working days. Frequent checks of the unfilled orders follow a Poisson distribution with a mean of two orders. A Poisson distribution is a discrete frequency distribution.

 

Has New Process, Inc. lived up to its internal goal? Cite evidence.

 

 4.   Recent information published by the U.S. Environmental Protection Agency indicates that Honda is the manufacturer of four of the top nine vehicles in terms of fuel economy.

 

 

a.   Determine the probability distribution for the number of Hondas in a sample of three cars chosen from the top nine.

 

b.   What is the likelihood that in the sample of three at least one Honda is included?

Scenario

You have been given the task of effectively communicating the organization’s mission, vision, and values to the new employees in your organization during new employee orientation. Your goal is to make sure that the employees understand what the organization’s mission, vision, and values are, as well as how they each fit into achieving the mission, vision, and values of the organization.

You want to make sure that this is something they will not forget soon, as it needs to be in their minds when they are working for the organization.

Task

Based on the scenario, complete the following tasks:

• Create a Microsoft PowerPoint presentation to go along with your oral presentation to the new employees. In your presentation, make sure that you have placed the oral part of the presentation into the Notes area of each slide. This will be your “script.”
• In addition, create a handout for the employees in a Microsoft Word document so they have something to take with them to remind them of what they learned.

Support your responses with relevant examples.

Cite any sources in APA format.

 

You are now ready to begin your adventure into the world of Python programming. The first step is to install Python on your computer. Please follow the steps in the first few paragraphs in the background information to accomplish this installation.

Python is a language which can be run as an interpreted language, as a script language or as a compiled language. At Google, python is one of the 3 “official languages” alongside with C and Java. Official here means that Googlers are allowed to deploy these languages to production services. Here you can read some more about Python and its current development.

In this module you will work with the Python Interpreter and Python Scripts. You should create your Python program by opening Python IDLE, choose File > New Window. Then you can write your own code or cut/paste existing codes from other sources (like tutorials). Make sure to save the code as .py file. If there exists .py file, then simply File > open. Run the program by clicking on the menu Run > Run Module F5.

Case assignment:

Your first programming assignment is about variables, expressions, statements and conditionals

• Read chapter 2 ( variable, expressions and statements) and 5 (Conditionals, only 5.1 through 5.7) in the online book of “Think Python: How to Think Like a Computer Scientist (Version 1.3.3)” http://www.greenteapress.com/thinkpython/thinkpython.pdf. Run all the examples and exercises in CH2, the examples 5.1 through 5.7 in CH5.
• Read the Instant Hacking tutorial in the background readings and Try the examples of Hello World, Area of a Rectangle, Feedback, and Flow. Run all the examples and exercises.

(a common mistake that occurs is that when you cut/paste the code directly from the tutorial, there will be extra empty spaces before certain lines, then you will encounter a syntax error message “unexpected indent” when you run the program. Fix the problem by deleting the extra indent.)

When you’ve done, insert all of the various program files into a single zip file and upload them to coursenet. Include a brief summary document in Word which explains what you have accomplished.

If you would like to know what students who took this class in the past said, please check here.

Case assignment expectations:

• Provide all the required program files.
• Provide a brief summary document discussing what you have accomplished.

Final draft

Same guidelines as for the first draft, just adding 3 to 4 pages for the previous paper and write Executive Summary for the whole paper the executive summary should be less than 2 pages (between 1 to 2 pages)
