MTH 156 Colorado State University Estimator New York Survey Data MCT 6 Report
Option #2: New York Survey DataA consulting firm was hired to conduct a survey on people living in
New York City. The survey was completed monthly for six months by 445
randomly-selected people in different boroughs. There were a number of
items on the survey, but six basic biographical items will be studied
for this exercise. The data for the people surveyed in one of these
monthly surveys can be found in the Excel file SURVEY. The variables that were used for the basic biographical data are found on the last page of the exercise.In this exercise, some of the estimation techniques presented in the
module will be applied to the New York survey results. You may assume
that these respondents represent a simple random sample of all potential
respondents within the community, and that the population is large
enough that application of the finite population correction would not
make an appreciable difference in the results.New York City governmental agency personnel like to have point
estimates regarding variables describing the biographical information of
the people living within the different boroughs. It is very helpful for
them to have some idea regarding the likely accuracy of these estimates
as well. Therein lies the benefit of the techniques presented in this
module and applied here.
Item A in the description of the data collection instrument lists
variables 1 through 5, which represent the respondent’s general attitude
toward each of the five boroughs. Each of these variables has
numerically equal distances between the possible responses, and for
purposes of analysis they may be considered to be of the interval scale
of measurement.
Determine the point estimate, and then construct the 95% confidence interval for μ1= the average attitude toward Manhattan.
Repeat part (a) for μ2 through μ5, the average attitudes toward Brooklyn, Queens, The Bronx and Staten Island, respectively.
Given the breakdown of responses for variable 6 (highest level of
education), determine the point estimate, and then construct the 95%
confidence interval for p6= the population proportion of doctoral degrees.
Given the breakdown of responses for variable 7 (marital status of
respondent), determine the point estimate, and then construct the 95%
confidence interval for p7 = the population proportion in the “single or other” category.
Assume the governmental agencies requested estimates of the mean
attitudes towards each borough with a margin of error of 0.05 for each
borough. If the governmental agency personnel want to have 95%
confidence that the sample mean will fall within this margin of error,
how large should the sample sizes be for each borough?
Requirements:
Your paper should be 2-3 pages in length (not counting the title
page and references page) and cite and integrate at least one credible
outside source. The CSU Global Library is a great place to find
resources. Your textbook is a credible resource.
Include a title page, introduction, body, conclusion, and a reference page.
The introduction should describe or summarize the topic or problem.
It might discuss the general applications of the topic or it might
introduce the unique terminology associated with the topic.
The body of your paper should address the questions posed in the
problem. Explain how you approached and answered the question or solved
the problem, and, for each question, show all steps involved. Be sure
this is in paragraph format, not numbered answers like a homework
assignment.
The conclusion should summarize your thoughts about what you have
determined from your analysis in completing the assignment. Nothing new
should be introduced in the conclusion that was not previously discussed
in the body paragraphs.
Include any tables of data or calculations, calculated values,
and/or graphs referenced in the paper. (Note: The minimum required
length excludes any tables or graphs.)
Document formatting, citations, and style should conform to the CSU Global Guide to Writing and APA Requirements (Links to an external site.). A short summary containing much that you need to know about paper formatting, citations, and references is contained in the Template Paper (Links to an external site.). In addition, information in the CSU Global Writing Center (Links to an external site.) has many helpful areas (Writing Tips, Template & Examples/Papers & Essays, Figures and Tables, and others).
NOTE: You MUST submit your Excel file with your
report. This will allow you to qualify for consideration for partial
credit if any errors are found in your report.

Chapter 16 Case Study
(Foot Locker), pages 618-619. (Start with “Supposing Foot Locker”) Hint: Use
the chi-square test of independence formula on page 610 to compute by hand or
go to: http://www.physics.csbsju.edu/stats/contingency_NROW_NCOLUMN_form.html (Links
to an external site.)Foot Locker in the Shoe MixFoot Locker, Inc., is the world's number one
retailer of athletic footwear and apparel. Headquartered in New York City, the
company has over 44,000 employees and 3369 retail stores in 23 countries across
North America, Europe, Australia, and New Zealand operating under such brand
names as Foot Locker, Lady Foot Locker, Kids Foot Locker, Footaction, Champs
Sports, and CCS. Foot Locker estimates that it controls about 18% of the U.S.
$15 billion athletic footwear market. The company intends to increase its share
of the worldwide market by adding additional stores and by growing its Internet
and catalog business.
In recent years, Foot Locker officials have
been rethinking the company's retail mix. Determining the shoe mix that will maximize
profits is an important decision for Foot Locker. By the year 2002, in an
effort to stock more lower-priced footwear, the company had reduced its
inventory of sneakers priced at $120 or more by 50%.
DISCUSSION
Suppose the data
presented below represented the number of unit sales (million $) for athletic
footwear in the years 2000 and 2012. Use techniques presented in this chapter
to analyze these data and discuss the business implications for Foot Locker.

Suppose Foot Locker
strongly encourages its employees to make formal suggestions to improve the
store, the product, and the working environment. Suppose a quality auditor
keeps records of the suggestions, the persons who submitted them, and the
geographic region from which they come. A possible breakdown of the number of
suggestions over a 3-year period by employee sex and geographic location
follows. Is there any relationship between the sex of the employee and the
geographic location in terms of number of suggestions? If they are related,
what does this relationship mean to the company? What business implications
might there be for such an analysis?

Chapter 12 Case
Study (Caterpillar), pages 471-472, question 1 only. Use an alpha of
.05. You need to submit your supporting formula work or work in
Excel.
The United States Department of Agriculture
(USDA), in conjunction with the Forest Service, publishes information to assist
companies in estimating the cost of building a temporary road for such
activities as a timber sale. Such roads are generally built for one or two
seasons of use for limited traffic and are designed with the goal of
reestablishing vegetative cover on the roadway and adjacent disturbed area
within ten years after the termination of the contract, permit, or lease. The
timber sale contract requires out sloping, removal of culverts and ditches, and
building water bars or cross ditches after the road is no longer needed. As
part of this estimation process, the company needs to estimate haul costs. The
USDA publishes variable costs in dollars per cubic-yard-mile of hauling dirt
according to the speed with which the vehicle can drive. Speeds are mainly
determined by the road width, the sight distance, the grade, the curves and the
turnouts. Thus, on a steep, narrow, winding road, the speed is slow; and on a
flat, straight, wide road, the speed is faster. Shown below are data on speed,
cost per cubic yard for a 12 cubic yard end-dump vehicle, and cost per cubic
yard for a 20 cubic yard bottom-dump vehicle. Use these data and simple
regression analysis to develop models for predicting the haul cost by speed for
each of these two vehicles. Discuss the strength of the models. Based on the
models, predict the haul cost for 35 mph and for 45 mph for each of these
vehicles.
