MATH 1342 Project Instructions
Given the data from the North Carolina State Center for Health and Environmental Statistics in
2001, create a well-organized, creative PowerPoint presentation that will analyze the given
information. The data, which is stored in the Excel file, named “Communication Project Data”
should be attached.
Consider the following points when creating the PowerPoint:
- Record the voice narrating the PowerPoint. You may wish to rehearse your
presentation before you record your voice.
- The PowerPoint should play automatically from slide-to-slide.
- The first slide should include your Name, course name and number (MATH 1342
Elementary Statistical Methods), and semester (Spring 2019).
- All slides should be grammatically correct and error free.
- All math content must be correct.
- The PowerPoint presentation should be uploaded into Canvas before the due date.
- This project will count as a test grade.
- Analyze the design of the study:
a. What sampling technique do you think was used to select the sample for the
b. What data collection method will give you a sample that is representative of
the population? Define the population and the sample of the study.
c. Classify each variable in the study as qualitative or quantitative? Explain why
you classified the variable in that way.
d. Use the data in the study to provide an example for each level of
measurement (nominal, ordinal, interval, or ratio). If any of the levels is
missing, propose a new variable to illustrate it.
e. Identify possible flaws or biases in the study.
- For any two of the qualitative type variables, construct a frequency table that gives
the counts and percentages of observations in each category (class) and a bar graph
or pie chart that better summarize the data. Use separate PowerPoint slide for each
of the two variables.
- Using the percentages from step 9 construct two 95% confidence intervals for the
population proportion. Interpret the results.
- For any two of the quantitative type variables, construct a histogram and comment
on the shape, and construct a table to show the mean, median, standard deviation,
the minimum value, and the maximum value. Use separate PowerPoint slide for each
of the two variables.
- Using the means and standard deviations from step 11 construct two 90% confidence
intervals for the population means. Interpret the results.
- A good friend of yours had a baby and gained approximately 30 pounds during her
pregnancy. Find the z-score, sketch the graph, and in writing explain to her why she
should not be too depressed over this occurrence.
- Construct a scatter plot of the data, calculate the correlation coefficient and make a
conclusion about the type of correlation between completed weeks of gestation and
weight of child (grams). Find the equation of the regression line and add the graph to
the scatter plot.
- Of particular interest will be incidents of low infant birth weight. Low birth weight is
commonly defined as less than 2500 grams. Construct the contingency table, that
shows the number of women who smoke and who did not smoke and the number of
babies with low birth weight. Compare the probabilities of a woman to have a baby
with low weight, if she smokes and if she doesn’t smoke. Make a conclusion.
- A government agency reports that the male to female ratio in 2018 was 102 to 100, i.
e. the chance to have a male baby is 50.5%. At α = 0.05 is there enough evidence to
reject the agency’s claim? Write the conclusion using complete sentences.
- Use the data in the study to find the probability that if you survey 20 women, at least
12 of them will have a son.
- Lastly, propose three other variables you would like to investigate in regard to
weight of the mother. Write the explicit question you would ask the mother prior to
delivery and in writing explain why you want to know that information.
- Save your file using your last name, first name initial, and the section number, i.e. for
John Smith from MATH 1342.01 it will be SmithJ.MATH1342.01.

Recovered from http://www.ebrary.com.libproxy.nau.edu Movie chief and creator Oscar Micheaux's works are thoroughly analyzed to contemporary producer D.W. Griffith's film, Birth of a Nation. Micheaux's film, Within Our Gates, similar to Griffith's film, glorifies an upbeat middle class couple, yet the social complexities and foundation accounts of these couples are altogether different. Griffith's character Elsie Stoneman is a special and fragile white northern lady who later grasps prejudice and experiences passionate feelings for a Klu Klux Klan part who saved her. Micheaux's Sylvia is a blended African American lady who does not originate from an advantaged family and is exceptionally autonomous. She begins to look all starry eyed at Dr. Vivian, not on the grounds that he protected her, and fund-raises for an underprivileged dark school. Micheaux's tale, The Forged Note: A Romance of the Darker Races, outlines Michaeux's philosophical control contrasted with Griffith's undaunted Manichean state of mind. The creator takes note of that Griffith's goals to clashes normally included power; Micheaux's goals were practiced by training. Micheaux's depiction of compensation is two sweethearts at long last combining as perfect partners. Griffith's compensations are vengeance and reimbursement. Both Micheaux and Griffith endeavored to depict the perfect average American culture, however with essential contrasts between the two depictions. Griffith needed this unspoiled symbol to stay with the racial oppressors and to keep up racial virtue. Micheaux needed others to have the capacity to get to the white collar class life. The creator relates that Micheaux's perspectives were from the base turning upward as underprivileged individuals endeavoring to end up white collar class, while Griffith's perspectives were starting from the top, depending on high society to develop the working class. Green, J. R. (2000). 8. In Straight Lick : The Cinema of Oscar Micheaux (pp. 123-136). Bloomington, US: Indiana University Press. Recovered from http://www.ebrary.com.libproxy.nau.edu The creator examines in detail the stereotyping and personification of African Americans as managed by Oscar Micheaux in his movies and especially the characters in his preparations. Micheaux's principle center in life was to inspire others, however stereotyping and personifications were frequently barricades for him. The creator considers the film The Exile by Micheaux and relates the battles of the movies characters Jean, Jango, and Edith to the greater social issues of African American generalizations among whites. The contention among Edith and Jango about instruction is contrasted with the contemporaneous supposition that African Americans amid the time of Prohibition were regularly overeducated for the employments they were performing. The creator features Micheaux's worries of the debasement of the nobility of African Americans by participating in occupations of ill-conceived business amid Prohibition. The film The Darktown Revue, the main show film by Micheaux, gives both positive pictures and negative racial generalizations which the creator portrays as intelligent contentions by Micheaux to represent the issue of African American twoness. Alain Locke's course of events of African American music intently coordinates Micheaux's own melodic encounters and can be utilized to distinguish Micheaux's movies from both a melodic and political point of view. The creator clarifies the word darktown as a dark network, yet additionally shows a more profound significance, that of a haven for African American minstrel performers getting away from the ethnic exaggerations of their stage exhibitions. These minstrel performers endured an obscured line between dread of disappointment or analysis and dread of damage or even passing. Green, J. R. (2000). 9. In Straight Lick : The Cinema of Oscar Micheaux (pp. 137-156). Bloomington, US: Indiana University Press. Recovered from http://www.ebrary.com.libproxy.nau.edu Oscar Micheaux's film The Darktown Revue is examined from the point of view of how Micheaux dealt with the many negative personifications of African Americans and correlations are attracted to the Fisk Jubilee Singers. The creator relates how the Fisk Jubilee Singers from the dark Fisk University in Nashville visited the eastern US amid the 1870's and were a triumph both monetarily and politically. This gathering of dark entertainers is uncovered as the gathering which made ready for future dark melodic theater and furthermore attempted to elevate the cartoon of Black Americans as saw from the prevalently white open. Examinations are attracted to G. D. Pike's account of the Fisk Singers and Micheaux's film The Darktown Revue as both utilized common personifications to impact change in their gatherings of people. The creator takes note of how the racial atmosphere in Micheaux's years was much more savage than the season of the Fisk Singers about sixty years sooner. Exaggeration in Micheaux's time was seen as a barricade for African American development. The creator clarifies the two demonstrations of the Darktown Revue and the cartoons exhibited. Micheaux's utilization of structure in the film is paradigmatically clarified as switching back and forth among positive and negative figures, depicted by the theme speaking to white collar class African Americans and the exhibitions including changed racial cartoons, individually. The cutting look of Micheaux is clarified as his focus on negative pictures. Differences to the Fisk Singers and Micheaux are noted as the Fisk Singers essentially utilized just positive pictures. The creator safeguards Micheaux's point of view on exaggerations and compliments his soul.>GET ANSWER
