Please see the attached problem write-ups. There are 3 of them to complete. Please be sure to pay attention to each question.
Module 6
Please write a report about the following:
Research and report on a topic that relates mathematics to art, music, science, or economics.
Make sure you describe the mathematical concepts that are present in the work and
what you understand about the mathematics. Your paper must be at least one full, singlespaced page long. Include a citation and a link to the source(s) you used.
Module 7
The problem you must solve is:
Answer each of the following questions in your own words. Do not copy and paste or
retype the questions themselves into your document, as this will cause unreliable
results at Turnitin.com. Simply provide the answers, in complete sentences.
Refer to this data on the U.S. Nursing Workforce from a report from the Department of
Health and Human Services.
1. What percentage of states has fewer than 850 registered nurses per 100,000 in
population? Does the collection of states represented by this percentage generally
represent a specific region of the country? If so, which region might this be; if not,
why not?
2. How many states have a number of registered nurses per 100,000 in their workforce
in the range of 800-1035?
3. According to Census 2000 and ACS 08-10, which age range has the lowest number
of registered nurses working?
4. According to Census 2000 and ACS 08-10, approximately what percentage of the
registered nursing workforce is 36-50 years old?
5. In which setting(s) did the estimated number of registered nurses experience a
decrease?
6. Overall, how do the graphs of the age distributions for the RN workforce and
the LPN workforce compare?
7. Describe 2 additional pieces of information that you can read from the data displays.
Module 8
The problem you must solve is:
Consider a common disorder, which we will call Z, that affects 18% of adults (18 years and over)
in the U.S. Fortunately, there is a genetic screening test for the gene that causes disorder Z. The
test is 98% accurate; that is, 98% of the people who take the test get the correct result (and 2%
of people tested get the wrong result).
In Johnsonville, the adult population is 150,000 and all the residents get tested for the gene
linked to disorder Z.
1.

3.
4.
How many of the residents of Johnsonville are likely to have the disease?
How many of the people who actually have the disease get a positive test result?
How many of the people who do not have the disease get a positive test result?
Of the people who get a positive test result, how many of them have the disease?
Convert this to a percentage: What percent of people who get a positive test results
actually have the disease?
5. Compare your results with the problem you solved in the discussion activity (M8D1).
Specifically, focus on the percent of people who get a positive result that actually have
the disease. Remember that both genetic tests were 98% accurate. Why were the
percentages so different? Do you think the rarity of the disease affects testing results?
Why or why not? Be sure to explain your reasoning mathematically.
