Assume
you are working for a local public health organization at the state level. Your
team wants to develop a program to prepare for a possible pandemic that is
spreading worldwide. View, “Laurie Garrett on Lessons From the 1918 Flu.” How
could knowledge of the course objectives help you make recommendations to your
organization?
BIO
500 Week 3 DQ 1
It is
time to relate the rules and concepts of probability to the practice of
statistics and experimentation. Sampling distributions provide the link between
probabilities and data. Recall that the sum of the probabilities of all
possible outcomes for a certain event must equal one. Because the variables
representing or describing a certain event can take on a range of values, the
frequency of each of those values forms a distribution of possible outcomes,
each with its own probability of occurrence. View “Central Limit Theorem”
(media piece). What is the significance of the frequency histogram illustrated
by dice and numbers in “Dice Combination?” How does this relate to the central
limit theorem provided in the media? Roll the dice, what were your odds? HINT:
Click on Dice Combination in the media. If you roll the dice, you have to count
the total number of two dice. There are two ways to check on your results
(Refer to the instructions by clicking Instructions); click on the dice
combinations and odds given in the frequency histogram and the table or click
the red bar at the right side of the media piece. Explore the basic principle
of probability through this media piece. Utilize the quiz to ensure that you
understand these basic principles. What is the significance of probability in
judgment and decision making in important aspects of health care? Explain your
response with an applicable example.

500 Week 4 Confidence Interval
Details:
In the
Topic 1 Assignment, you compared the BMI values from Data Set 1 (in the
appendix of the textbook) from a perspective of measuring the center and
variation of the data. Chapters 5 and 6 in the textbook allow you to use more sophisticated
tools to estimate the parameters of a population.
Refer to
Data Set 1 in Appendix B and use the sample data with Excel and/or SPSS to
accomplish the following:
Construct
a 99% confidence interval estimate of the mean body mass index for men.
Construct
a 99% confidence interval estimate of the mean body mass index for women.
Compare
and interpret the results. It is known that men have a mean weight that is
greater than the mean weight for women, and the mean height of men is greater
than the mean height of women. Do men also have a mean body mass index that is
greater than the mean body mass index of women?
APA
format is not required, but solid academic writing is expected.
This
assignment uses a grading rubric. Instructors will be using the rubric to grade
the assignment; therefore, students should review the rubric prior to beginning
the assignment to become familiar with the assignment criteria and expectations
for successful completion of the assignment.
You are
not required to submit this assignment to Turnitin.
BIO
500 Week 5 Hypothesis Testing
Details:
Chapter
8 of the textbook explains how to make inferences from two samples using the
process of hypothesis testing.
Refer to
Data Set 1 in Appendix B and test the claim that the mean body mass index (BMI)
of men is equal to the mean BMI of women.
Use
Excel and/or SPSS to perform the hypothesis test.
Assume
that the two samples are independent simple random samples selected from
normally distributed populations. Do not assume that the population standard
deviations are equal.
Use
“Example Hypothesis Test of Treatment for Bipolar Depression” on page 391 of
the textbook as a guide for your test.

500 Week 8 BMI Statistical Report
Details:
Write a
750-1000 word statistical laboratory report using the guidelines in the
assigned article, “How to Write a Statistical Report.” This statistical report
is not meant to be an APA report or a multiple-page scholarly treatise. The
goal is that you become familiar with the formal report format that you will
use whenever you are reporting statistical analysis. The report format includes
the following sections: Abstract, Purpose, Methods, and Results.
Assume
that you are asked to perform an exploratory data analysis in which the
emphasis is to compare the difference between the body mass index (BMI) values
of men and women. Use Excel and/or SPSS to create reports and run analyses on
the data for the Data Set 1 in Appendix B of your textbook.
Assume
you are a biostatistics analyst and you received a request from the director of
the nutrition program to perform the analysis. The director is developing an
obesity program for the state and has obtained the data set from the National
Center for Health Statistics (NCHS). Because it has been some time since the
director has had a statistics course, any points that would make your analysis
easier to understand would be appreciated.
Generate
appropriate histograms or box plots. Find appropriate statistics that will help
to understand the data set. Are there any notable features? Are there any
outliers? Describe the key elements of center, variation, distribution, and
outliers.
A
minimum of three scholarly references are required.
While
APA format is not required for the body of this assignment, solid academic
writing is expected, and in-text citations and references should be presented
using APA documentation guidelines, which can be found in the APA Style Guide,
located in the Student Success Center.

of variance (ANOVA) for the data in “From Data to Decision” on page 565 of the
textbook.
APA
format is not required, but solid academic writing is expected.
Question
4 For the following assignment, use the Rank
Correlation that was demonstrated in Chapter 12 of the textbook (page 566).
Utilizing Excel or SPSS:
Use a
rank correlation coefficient to test for a correlation between two variables.
Use a
significance level of ?=0.05.
The new
health care program in the United States makes provisions for capitation
programs where health care insurers work with clinical facilities to perform
risk analysis of patients to determine the cost of providing care. The
following assignment might be used to assess how much a person smokes.
When
nicotine is absorbed by the body, cotinine is produced. A measurement of
cotinine in the body is therefore a good indicator of how much a person smokes.
The reported number of cigarettes smoked per day and the measured amounts of
cotinine (in ng/ml) are provided. (The values are from randomly selected
subjects in a National Health Examination Survey.) Is there a significant
linear correlation? How would you measure the cotinine level in the body?
Explain the result.
Refer to
the “Rank Correlation Table.”
