The CEO of your company has asked you, the human resource manager,
to conduct a study to determine whether or not male managers and
female managers perceive leadership styles differently and, if
differences are found, to develop a training program that will benefit
gender differences in leadership. To this end you selected, randomly, 10
male managers and 10 female managers to participate in your study. To
each manager a leadership style survey questionnaire was administered.
The questionnaire chosen was the Blake & Mouton Managerial Grid as
it assesses leadership behavior. The numeric raw data results of the 18
question study are as follows:

Complete the following in a single MS Word or Excel document:
1. Calculate the mean, median, mode, variance, and standard
deviation for the numeric data.
2. Construct a histogram, pie, or Stem-Leaf Display chart
encompassing the mean leadership scores for both male and female
managers. Use an online interactive program to formulate your
histogram, pie charts, or Stem-Leaf Display.
3. Construct a histogram for median score values for male managers
and female managers with respect to management style.
4. Analyze the data and present preliminary conclusions based on
answers to questions #2 and #3 with respect to the leadership style
differences between male and female managers.
5. Offer a brief 5-point summary of the training program you might
use to strengthen the leadership deficiencies found in either or both the
male and female manager leadership style.
Any conclusion drawn for the t-test statistical process is only as good as
the research question asked and the null hypothesis formulated. T-tests
are only used for two sample groups, either on a pre post-test basis or
between two samples (independent or dependent). The t-test is
4. optimized to deal with small sample numbers which is often the case
with managers in any business. When samples are excessively large the t
test becomes difficult to manage due to the mathematical calculations
involved.
Calculate the “t” value for independent groups for the following data
using the formula presented in the module. Check the accuracy of your
calculations. Using the raw measurement data presented above,
determine whether or not there exists a statistically significant difference
between the salaries of female and male human resource managers using
the appropriate t-test. Develop a research question, testable hypothesis,
confidence level, and degrees of freedom. Draw the appropriate
conclusions with respect to female and male HR salary levels. Report
the required “t” critical values based on the degrees of freedom. Your
response should be 2-3 pages.

7. all the paper that is used in them without the paper getting jammed. The
CEO asks you to determine the thickness of paper that the machines
must be able to handle to achieve this target. Using the data provided
(located in the Doc Sharing area as Worksheet AUO_MGT 340_M3-
rev.xls), prepare a 6-8 slide PowerPoint presentation directed to the CEO
of John and Sons Company detailing your findings. Make sure you
include the appropriate confidence limits for the thickness of paper that
the machines must be able to handle. Use the notes section in PPT to
clarify your talking points. You must use at least one data chart, one
additional graphic and three additional resources (one of which may be
your text book) in your presentation to support your analysis.
