Thomas Edison State STA 201 Full course including Week 1 to 9 Written Assignment and Final Project
Written Assignment 1

Write a short introduction of yourself and your interest in statistics and provide an example you use statistics in everyday life.

Written Assignment 2
Case Study: Greatest American Screen Legends (p.31): Answer questions a, b, c.

a. Identify the population.

b. Identify the sample.

c. Is the sample representative of the population of all U.S. moviegoers? Explain your answer.

Written Assignment 3
Write your response to the following question.

We often hear you can lie with statistics. This is one way of saying statistics can be easily miscommunicated. Find one example of how statistics are miscommunicated and explain why there was a miscommunication and what you would do to correct this problem.

Written Assignment 4
In your own words, interpret the data and note the shape of the distribution of the data provided from Case Study: Highest Paid Women (Chapter 2, p. 35). To help guide your interpretation, include the following:

· frequency table,

· stem and leaf plot

· histogram

· sample mean and median

· sample standard deviation.

You must calculate results by hand (though you may use any technology of your choice to verify your answers).

Written Assignment 5
Write your response to the following topic.

Using probability: How can you use probability to improve your chances of winning at a casino? Provide specific examples using concepts learned in this module.

Written Assignment 6
Case Study: Texas Hold’em (p.209): Answer a,b,c,d,e,f,g. You must calculate results by hand (though you may use any technology of your choice to verify your answers).

a.) The probability that you are dealt pocket aces is 1/221, or 0.00452 to three significant digits. If you studied either section 4.5 and 4.6 or section 4.8, verify that probability.

b.) Using the result from part (a), obtain the probability that you are dealt “pocket kings”.

c.) Using the result from part (a) and your analysis in part (b), find the probability that you are dealt a “pocket pair”, that is, two cards of the same denomination.

d.) contains at least 1 card of your denomination (Hint: Complementation rule.)

e.) gives you “trips” that is , contains exactly 1 card of you denomination and 2 other unpaired cards.

f.) gives you “quads” that is, contains 2 cards of you denomination.

g.) gives you a “boat” that is, contains 1 card of you denomination and 2 cards of another denomination.

Written Assignment 7
Write your responses to the following topic.

Outliers: We know many types of data fall into a normal distribution with most of the observations falling toward the middle. However, sometimes data are outliers or data that are very different – larger or smaller – from the rest of the members of the sample. Think of an example in the real world of an outlier and discuss its effect.

Written Assignment 8
The written assignment draws on case study discussion exercises at the end of chapter. When preparing your assignment, please identify each answer clearly by question and its number.

Case Study: Chest Sizes of Scottish Militiamen (p.295): Answer a,b,c,d. You must calculate results by hand (though you may use any technology of your choice to verify your answers).

a.) Construct a relative-frequency histogram for the chest circumference data, using classes based on a single value.

b.) The population mean and population standard deviation of the chest circumferences are 30.85 and 2.07, respectively. Identify the normal curve that should be used for the chest circumference.

c.) Use the table on page 254 to find the percentage of militiamen in the survey with chest circumferences between 36 and 41 inches, inclusive. Note: As the circumferences were rounded to the nearest inch, you are actually finding the percentage of militiamen in the survey with chest circumference between 35.5 and 41.5 inches.

d.) Use the normal curve you identified in part (b) to obtain an approximation to the percentage of militiamen in the survey with chest circumference between 35.5 and 41.5 inches. Compare you answer to the exact percentage found in part (c).

Written Assignment 9
Write your responses to the following topic.

Errors in testing: Think of one example of a Type I and Type II error in everyday life and comment on the ramifications of those errors.

Final Project

You are required to complete a final project. Please consult the Course Calendar for the due date.
Project Description
Statistics is about more than calculations. It is about turning data into information and using this
information to understand the population. A statistician will be asked to help solve real world problems by designing a study, collecting data, analyzing the data, and writing up the results. As a final project, you will be asked to do something similar. Though the design and data collection will be done for you, you will be asked to analyze the data using the appropriate tests (ensuring the data are distributed normally) and write up the results, using statistical evidence to support your findings. Lastly, you will be asked to include recommendations, that is, apply the results to solve the real world problem.
In your paper, explain why you chose each statistical test, figure, or procedure.
The problem:
Due to financial hardship, the NYKE shoe company feels they only need to make one size of shoes, regardless of gender or height. They have collected data on gender, shoe size, and height and have asked you to tell them if they can change their business model to include only one size of shoes –
regardless of height or gender of the wearer. In no more 5-10 pages (including figures), explain your
recommendations, using statistical evidence to support your findings. The data found are below:
Shoe Size Height Gender
5.00 63.00 Female
7.50 70.00 Female
9.00 70.00 Female
7.00 64.00 Male
