This guide will demonstrate how to complete the Chamberlain University MATH 225N Week 7 Discussion: Hypothesis Testing assignment based on general principles of academic writing. Here, we will show you the A, B, Cs of completing an academic paper, irrespective of the instructions. After guiding you through what to do, the guide will leave one or two sample essays at the end to highlight the various sections discussed below.
How to Research and Prepare for MATH 225N Week 7 Discussion: Hypothesis Testing
Whether one passes or fails an academic assignment such as the Chamberlain University MATH 225N Week 7 Discussion: Hypothesis Testing depends on the preparation done beforehand. The first thing to do once you receive an assignment is to quickly skim through the requirements. Once that is done, start going through the instructions one by one to clearly understand what the instructor wants. The most important thing here is to understand the required format—whether it is APA, MLA, Chicago, etc.
After understanding the requirements of the paper, the next phase is to gather relevant materials. The first place to start the research process is the weekly resources. Go through the resources provided in the instructions to determine which ones fit the assignment. After reviewing the provided resources, use the university library to search for additional resources. After gathering sufficient and necessary resources, you are now ready to start drafting your paper.
How to Write the Introduction for MATH 225N Week 7 Discussion: Hypothesis Testing
The introduction for the Chamberlain University MATH 225N Week 7 Discussion: Hypothesis Testing is where you tell the instructor what your paper will encompass. In three to four statements, highlight the important points that will form the basis of your paper. Here, you can include statistics to show the importance of the topic you will be discussing. At the end of the introduction, write a clear purpose statement outlining what exactly will be contained in the paper.

How to Write the Body for MATH 225N Week 7 Discussion: Hypothesis Testing
After the introduction, move into the main part of the MATH 225N Week 7 Discussion: Hypothesis Testing assignment, which is the body. Given that the paper you will be writing is not experimental, the way you organize the headings and subheadings of your paper is critically important. In some cases, you might have to use more subheadings to properly organize the assignment. The organization will depend on the rubric provided. Carefully examine the rubric, as it will contain all the detailed requirements of the assignment. Sometimes, the rubric will have information that the normal instructions lack.
Another important factor to consider at this point is how to do citations. In-text citations are fundamental as they support the arguments and points you make in the paper. At this point, the resources gathered at the beginning will come in handy. Integrating the ideas of the authors with your own will ensure that you produce a comprehensive paper. Also, follow the given citation format. In most cases, APA 7 is the preferred format for nursing assignments.
How to Write the Conclusion for MATH 225N Week 7 Discussion: Hypothesis Testing
After completing the main sections, write the conclusion of your paper. The conclusion is a summary of the main points you made in your paper. However, you need to rewrite the points and not simply copy and paste them. By restating the points from each subheading, you will provide a nuanced overview of the assignment to the reader.
How to Format the References List for MATH 225N Week 7 Discussion: Hypothesis Testing
The very last part of your paper involves listing the sources used in your paper. These sources should be listed in alphabetical order and double-spaced. Additionally, use a hanging indent for each source that appears in this list. Lastly, only the sources cited within the body of the paper should appear here.

Sample Answer for MATH 225N Week 7 Discussion: Hypothesis Testing
Our Week 7 initial prompt / cue is a little more open ended and vague than perhaps what might be usual so I wanted to provide you with something to help guide you a little bit. I won’t share the raw concrete data with you or any of the Excel spread sheets that I used until later in the Week 7. Notice that the assignment does not necessarily require you to provide data or to go through all of the finer and more technical details of all of this ( a full blown hypothesis testing example ) but that notwithstanding, the more thought you put into this assignment and the more details that you provide, the better. Please note my follow up Post to this Post where I give some details about where the calculated z value ( the calculated value for the test statistic ) would come from if an Excel spread sheet had not been used to get it. Thanks Friends and Best Wishes and Good Luck !!
Describe a hypothesis test study that would help your work or conclusions in some way. Describe what variable would be tested and what would be your guess of the value of that variable. Then include how the result, if the null were rejected or not, might change your conclusions or actions in some way.
My research question is: using the May 2009 data set, determine if there is sufficient evidence to conclude that the average amount of births is less than 5000 in the United States and territories, at the alpha significance level of 0.01
We will use the appropriate data and the appropriate spread sheet and the appropriate sheet within the correct spread sheet to calculate the calculated value for the test statistic and to calculate the P-value.
If the P-value is greater than the alpha significance level, the decision would be Do Not Reject the Null Hypothesis
If the P-value is smaller than the alpha significance level, the decision would be Reject the Null Hypothesis
I am using the alpha significance level of 0.01
So for me here
Based on my research question above, my hypotheses are:
( Pretend that there is a colon with two dots in each of those instead of the three dots !! I could not seem to get a colon to go in there !! )
From the Excel spread sheet provided elsewhere ( attached to another Post ) ( the hypothesis testing calculator spread sheet ) , using the 52 values for births from my May 2009 data set, the sample mean was
and the population standard deviation was
and the alpha significance level was as above and the hypothesized value from the null hypothesis was 5000 and the sample size of course was
The output included a calculated value for the test statistic of
and a P-value of
and based on P-value > alpha significance level
that is 0.9436 > 0.01
the decision of course was Do Not Reject the null hypothesis
which is Do Not Reject
The interpretation and conclusion therefore is as follows:
At the
significance level and for these particular collected and analyzed sample data, there is NOT sufficient sample evidence to conclude that the average amount of births is less than 5000 in the United States and territories.
The reasons I would analyze the Births, Deaths, Marriages, Divorces data for the 50 States and other areas such as Washington DC and Puerto Rico and other similar places ( such as perhaps Guam / US Virgin Islands ) is to get a feel for how much healthcare capacity is needed for delivering babies and for caring for the family from before conception to long after the actual birth. Also, noting Deaths data and trends also foreshadows the need for healthcare capacity in that we might surmise if the overall population is perhaps getting older on average or sicker on average or what not – again foreshadowing the healthcare capacity that we might need to build and maintain. Keeping track of Marriages data also foreshadows the need for healthcare capacity as increases in Marriages for example might also foreshadow more subsequent births and the need for more healthcare capacity to accommodate that.
Thanks Friends and take good care and best wishes too !!

Sample Answer 2 for MATH 225N Week 7 Discussion: Hypothesis Testing
Hello Professor and classmates:
I’d like to investigate follow-up after discharge for COVID-19 patients and how that relates to any subsequent hospitalization later for cardiovascular issues. We know that COVID-19 makes people hypercoagulable which increases risk of complications and even after recovery (Ciaburri, 2020), and some COVID-19 patients return to the hospital with cardiovascular complications (Rastogi and Twarei, 2020). I would hypothesize that patients who follow up with their doctors for venous thromboembolism (VTE) prophylaxis post discharge have better 6-month hospital readmission rates for cardio-vascular event compared to patients who do not follow up. Readmission in 6 months is my variable X, and this is a population proportion test.
My hypothesis could be a two-tailed test with one being no admissions in 6 months and the other being any admission in 6 months. As per our lesson, I’d write the claim first, which may be the null or the alternative hypothesis, and then write the complement to the claim (Chamberlain University, 2021). My null hypothesis for patients who comply with follow up is no cardio-vascular related readmissions, or Ho p = 0, and the alternative would be Ha p ≠ 0.
I hypothesize that receiving proper care in the recovery phase of COVID-19 will prove beneficial in preventing readmissions. If the numbers prove me wrong, then I must reject my null hypothesis, and “assume there is enough evidence to support the alternative hypothesis” (Holmes et al., 2018, p. 403).
As per the Chamberlain University on-line lesson, failure to reject the null hypothesis does not mean we have to accept the alternative hypothesis (2021). So, does that also mean that rejecting the null does not mean we accept the alternative hypothesis, or simply that we need more data? According to Ciaburri (2020), almost a third of COVID-19 patients experienced thrombotic complications, but age was also an independent risk factor. That information may cause me to rethink my hypothesis, but as a nurse, I would still urge patient education upon discharge that includes following up with the doctor as an outpatient.

Sample Answer 3 for MATH 225N Week 7 Discussion: Hypothesis Testing
MY TAKE ON P-VALUES, ALPHA SIGNIFICANCE LEVELS, and the “DECISION”
The alpha significance level is decided upon and stated and declared by the researcher( s ) at the very beginning of starting to think about and make a plan for an intended research effort. Alpha significance levels are not calculated from a formula and they are NOT decided upon “after the fact.”
The most common value for the alpha significance level used in the so-called “real world” is alpha = 0.05
However, once in a while in the real world, I think researchers find it prudent to use an alpha significance level of alpha = 0.01
The commonly used alpha significance level of 0.05 is related to the commonly used confidence level for confidence intervals in Week 6 of our course which as you recall was a confidence level of 95%
In a statistics course however ( for variety and practice among other reasons ) several different values for the alpha significance level can show up in various problems and exercises.
The calculated value for the test statistic AND the P-Value are BOTH calculated from sample data.
The decision is based on either comparing and contrasting the alpha significance level with the calculated P-Value OR by comparing the calculated value for the test statistic with the picture of the rejection region ( also called a critical region ) .
Thanks Friends and Good Luck and Best Wishes and please see the slides here for some more information and background about these particular topics.

Sample Answer 4 for MATH 225N Week 7 Discussion: Hypothesis Testing
Hypothesis Test problems and exercises probably have more steps for lack of a better way of putting it than perhaps anything else that we study or learn about in the course.
So the slides here are offered to you in order to hopefully help you keep all those steps straight and organized and so forth.
What will probably be more confusing to many of you is that many of the Knewton problems and exercises in the Week 7 homework only focus on doing certain parts or steps of the process and not always “the whole process from beginning to end.”
Does that make any sense ? If it does not make total sense now, what I meant here will be clear to you by the time you finish all of your Week 7 Knewton Homework.
Thanks Friends and these slides here are a great guide / template / road map as you try to make sense out of what we are trying to teach you during Week 7 of the course.
Thanks again Friends and take good care and Best Wishes too !!
