geographic regions across the United States. All 10 regions reported growth in
2013. The Southeast and Gulf Coast regions reported growth of 4.7% and 13.86%,
respectively. A characteristic description of the accounting firms in the
Southeast and Gulf Coast regions included the number of partners in the firm.
The fileAccountingPartners2contains the number of partners.
A.At the 0.05 level of significance, is there evidence of a
difference between Southeast region accounting firms and Gulf Coast accounting
firms with respect to the mean number of partners?
B.Determine thep-value and interpret its meaning.
C.What assumptions do you have to make about the two populations in
order to justify the use of thettest?
10.17Brand valuations are critical to CEOs, financial
and marketing executives, security analysts, institutional investors, and
others who depend on well-researched, reliable information needed for assessments,
and comparisons in decision making. Millward Brown Optimor has developed the
BrandZ Top 100 Most Valuable Global Brands for WPP, the world’s largest
communications services group. Unlike other studies, the BrandZ Top 100 Most
Valuable Global Brands fuses consumer measures of brand equity with financial
measures to place a financial value on brands. The fileBrandZTechFincontains
the brand values for two sectors in the BrandZ Top 100 Most Valuable Global
Brands for 2014: the technology sector and the financial institutions sector. (Data
extracted frombit.ly/18OL5Mu.)
A.Assuming that the population variances are equal, is there
evidence of a difference between the technology sector and the financial
institutions sector with respect to mean brand value? (Usea=.05.)
B.Repeat (a), assuming that the population variances are not equal.
C.Compare the results of (a)
and (b).
10.26The fileConcrete1
contains the compressive
strength, in thousands of pounds per square inch (psi), of 40 samples of concrete
taken two and seven days after pouring. (Data extracted from O. Carrillo-Gamboa
and R. F. Gunst, “Measurement- Error-Model Collinearities,â€Technometrics, 34 (1992): 454–464.)
A.At the 0.01 level of significance, is there evidence that the mean
strength is lower at two days than at seven days?
B.What assumption is necessary about the population distribution in
order to perform this test?
C.Find thep-value in (a) and interpret
its meaning.

Essay:
Write a paper that
considers ethical issues in business statistics and discuss how your personal
values can be applied to them. This assignment is primarily introspective in
nature and students will be given significant latitude in addressing specific
questions. Specifically, provide the following in your paper:
Include
a brief introduction that outlines your paper.
Address
the following question: Which ethical guideline(s) from the articles is
(are) most applicable to you and why? How does this article (or how do the
articles) affect your personal decision making related to statistics and
ethics?
How
can the ethical issue(s) raised be addressed from a Christian worldview?
In other words, what guidance, using principles from a Christian worldview
perspective, could be applied to understand and address these ethical
issues? The following GCU websites may be helpful: (a) Doctrinal Statement
(http://www.gcu.edu/About-Us/Doctrinal-Statement.php)
and (b) Mission and Vision (http://www.gcu.edu/About-Us/Mission-and-Vision.php.)
In
addition to addressing these questions, the student may also frame the
issue using ethical theories (utilitarianism, Kantian ethics, distributive
justice, virtue ethics, and covenantal ethics). Note, however,
that the previously posed questions about Christian worldview must still
be addressed.
Provide
a brief conclusion that summarizes your perspectives.
Use external citations.
Your paper should have at least six external citations (in addition to any
Biblical citations) to help frame the issue. Wikipedia citations are
not allowed.
