Analysis of Biostatistical Article

Identify a peer-reviewed article from the South University Online Library that presents statistical analysis of a pertinent topic of public health interest or importance. Provide a link to this article and give a brief summary of the article, including hypotheses, methods, and findings. Research the topic and available data sources. On the basis of the biostatistical methods you have learned about in this course, analyze the article and its findings.

Here are some points to consider in your analysis:

What data are available on this topic?

What data does the article use?

Discuss the level of measurement, assumptions that can be made, statistics that can be calculated from these data, and the general quality of the data.

What is the type of study or study design used?

Explain the type of biostatistical study design that the author has used.

Describe the hypothesis or hypotheses that the author intends to test.

Explain the statistics that the author uses to test these hypotheses.

What are the article’s statistical findings?

Describe the statistical results of the author’s analysis.

Provide a substantive interpretation of these findings (What do the results mean in relation to the hypotheses and the public health topic?).

Describe the author’s recommendations about this topic based on his or her findings and hypotheses.

If you had been the author, what changes, if any, would you have made in the study you analyzed?

Discuss whether the author made any statistical errors.

Were the correct data used for the questions asked?

Were the correct data available?

Were the correct statistics used for the data available?

What other data might you want to collect and why?

Do the statistical findings support the author’s conclusions?

Write a 15–20-page, double-spaced paper in Word format. Apply APA standards to citation of sources. Utilize at least 7–10 scholarly sources in your research and be sure to include a references page. Write in a clear, concise, and organized manner; demonstrate ethical scholarship in accurate representation and attribution of sources; and display accurate spelling, grammar, and punctuation.

The estimate must be within 0.5 milligrams of the population mean.a)Determine the minimum required sample size to construct a 95% confidence interval for the population mean. Assume the population standard deviation is 2.8 milligramsb) Repeat part A using a 99% confidence intervalc) Which level of confidence requires a larger sample size? Explain

## Current Events Reminder During the term, you are responsible for highlighting,

Current Events Reminder During the term, you are responsible for highlighting, given the objectives of this course, one current event discussed in a news publication or news website. Post in Unit 6 under “Current Events”. Your initial post should include a summary of the event or topic, its relationship with our learning in this course, and the location of the source material. The intent is to begin a discussion about the material that will enhance learning about the topics in this course. In the unlikely event that you choose a topic that someone else simultaneously posts, that is fine. Do check to see what topic threads are already being discussed before you select your topic. To help us follow each event “thread,” each new current event should be a primary post. All responses to it should be posted as a reply. In your replies, strive to examine the event from the perspective of the topics in this course.

## Government agencies carefully monitor water quality and its effect on wetlands

Question: Identify the implied population in the information here. Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

## Let Y denote the number of students on his bus. Compute the expectations and variances of X and Y:

Four buses carrying 145 high school students arrive to Montreal. The buses carry, respectively, 34, 44, 26, and 41 students. One of the studetns is randomly selected. Let X denote the number of students that were on the bus carrying this randomly selected student. One of the 4 bus drivers is also randomly selected. Let Y denote the number of students on his bus. Compute the expectations and variances of X and Y:

Pocket Nim) Consider a game of Nim in which the players have some number of chips in theirpockets. A legal move is either one of the usual legal moves of Nim, or involves moving some positivenumber of chips from the player’s pocket on to one of the piles. (Notice that no chip is ever returnedto a pocket.)(a) Show that the game is progressively bounded.(b) Find the sets N and P .(c) Describe the winning strategy.
