Grossmont College Introduction to Hypothesis Testing Discussion
The Pew Research Center reported in 2018 that 68% of U.S. adults rated "reducing health care costs" as a national priority. This year a survey is conducted with a national sample of 1,505 U.S. adults selected by a combination of landline and cell phone random digit dials. This year's survey finds that 70% of the sample says that "reducing health care costs" is a national priority.
We test the following hypotheses:
H 0: The proportion of U.S. adults this year who rate "reducing health care costs" as a national priority is still 0.68.
H a: The proportion of U.S. adults this year who rate "reducing health care costs" as a national priority is greater than 0.68.
The P-value is 0.045. At a 5% significance level, we would reject the null hypothesis and concluded that the proportion of U.S. adults this year who rate "reducing health care costs" as a national priority is greater than 0.68.
Explain the P-value in the context of this issue.

Managerial Quality report + excel file APA style
Option #2: Quality of Cerámica América SinksCerámica América makes both commercial and home sinks, toilets, and tile throughout Latin America. There have been many complaints that its commercial sinks are of poor quality. Recently, a new type of home sink, Modelo Americano, has been developed. The company hopes that this new model is of better quality. Quality Control tests sinks using the following three tests:Cracked or Chipped Ceramic:Pass (P) or Fail (F)Glaze Quality:Pass (P) or Fail (F)Stress TestPass (P) or Fail (F)A sink gets a “Passing” grade if it passes all three of the above Traditionally, 85% of its commercial sinks have gotten a “Passing” grade. Cerámica América would like to see if its passing rate is better than the traditional rate. Recently, 200 Modelo Americano sinks were randomly chosen from its manufacturing plants. The complete data set is in the file named Sinks.Managerial ReportPrepare a report (see below) for Cerámica América that summarizes your assessment of its Modelo Americano sinks. Be sure to include the following seven items in your report.To summarize the data, compute the proportion of all sinks that“Passed” the Cracked or Chipped test.“Passed” the Glaze Quality test.“Passed” the Stress Test.Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that got a “Passing” grade.Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that passed the Cracked or Chipped test.Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that passed the Glaze Quality test.Develop the 98% confidence interval for the proportion of all Modelo Americano sinks that passed the Stress Test.Conduct a hypothesis test (using either the p-Value Approach or the Critical Value Approach) to determine if the proportion of all Modelo Americano sinks that get a “Passing” grade is larger than the than the traditional “Passing” rate. Use α = 0.02. Do not forget to include the correctly worded hypotheses and show all the steps required to conduct the hypothesis test.What advice would you give to Cerámica América based upon your analysis of the data? What is the magnitude of the improvement (if any)? How can this study be improved?Write a report that adheres to the Written Assignment Requirements under the heading “Expectations for CSU-Global Written Assignments” found in the CSU-Global Guide to Writing and APA Requirements. As with all written assignments at CSU-Global, you should have in-text citations and a reference page. An example paper is provided in the MTH410 Guide to Writing with Statistics. (link provided at the bottom of the page)Submit your Excel file in addition to your report.Requirements:Paper must be written in third person.Your paper should be four to five pages in length (counting the title page and references page) and cite and integrate at least one credible outside source. The CSU-Global Library is a great place to find resources.Include a title page, introduction, body, conclusion, and a reference page.The introduction should describe or summarize the topic or problem. It might discuss the importance of the topic or how it affects you or society as a whole, or it might discuss or describe the unique terminology associated with the topic.The body of your paper should answer the questions posed in the problem. Explain how you approached and answered the question or solved the problem, and, for each question, show all steps involved. Be sure this is in paragraph format, not numbered answers like a homework assignment.The conclusion should summarize your thoughts about what you have determined from the data and your analysis, often with a broader personal or societal perspective in mind. Nothing new should be introduced in the conclusion that was not previously discussed in the body paragraphs.Include any tables of data or calculations, calculated values, and/or graphs associated with this problem in the body of your assignment.Document formatting, citations, and style should conform to the CSU-Global Virtual Library CSU-Global Guide to Writing and APA: Introduction. A short summary containing much that you need to know about paper formatting, citations, and references is contained in the New Sample APA Paper. In addition, information in the CSU-Global Virtual Library under the Writing Center/APA Resources tab has many helpful areas (Writing Center, Writing Tips, Template & Examples/Papers & Essays, and others).

UAGC Math Independent and Dependent Variable Discussion
There are five parts to this discussion: Read, identify three different variable pairs, create table, create graph, describe in words.
Prepare: Prior to beginning work on this discussion, read Chapter 9: Modeling Our World and Chapter 10: Modeling with Geometry in your course text, especially pages 532-3 & 536-9.
For this discussion, identify three different variable pairs in which two quantities appear to be related from either recent news stories, the web, or that you encounter in your everyday life. Each variable pair should come from a different source (as illustrated in the week 4 Discussion Sample) and there should be three sets of paired variables total.
Important note: Only one of the variables can use “time” as an independent variable. For example, you cannot have your variable pairs be (time, dependent variable 1), (time, dependent variable 2) and (time, dependent variable 3). However, you can have your variable pairs be (time, dependent variable 1), (independent variable 2, dependent variable 2) and (independent variable 3, dependent variable 3).
For inspiration, use the examples listed in the solution to Example 1 on p. 537 of the text, or the Week 4 Discussion Sample download, MAT205.W4.DiscussionSample.pdf. Be sure to select different examples!
Create Table
After you have identified three different variable pairs (from distinct sources), make a table of between 10 and 20 entries of data values for each of your variable pairs.
Create Graph
Then, graph your data values for each variable pair and describe in words the function that relates the variables. For each pair, write down at least five (5) points on the graph. Draw the graph using paper & pencil or use an online graphing calculator like Desmos Graphing Calculator (Links to an external site.).
Describe Your Results in Words
For each of the pairs you listed, identify the dependent and independent variables and briefly describe the relationship.
See the week 4 Discussion Sample to see how these go (You must use different examples; you should complete three examples total).
Your initial post should be at least 250 words in length. It should show all the required math work and explain all the steps. Also include a simple reference for any scholarly resource you used. For example: Washington Post dated August 13, 2018 or retrieved from <url-address> or I consulted example 1 on p. 537 of the text.
Your initial discussion thread is due on Day 4 (Friday), and you have until Day 7 (Monday) to respond to your classmates. Your grade will reflect both the quality of your initial post and the depth of your responses. Carefully review the Grading Rubric for guidance on how your discussion will be evaluated.
The Easy Way to Plot and Graph Points
Use the Desmos Graphing Calculator (Links to an external site.): (You need not create an account.)
Click on the “+” at the top left corner.
Select “table” from the drop-down menu.
Type in your points. If your point is (2, 30), then x1 is 2 and y1 is 30.
** If your points contain any values beyond ±10, click the minus sign in the upper right-hand corner a few times to zoom out so you can see the points. **
To add a line connecting the points:
Click and hold on the circle with four dots on it (next to y1). Click the circle next to “Lines” to show the connecting line. Your graph is done.
To share the graph, take a screenshot. [This site will show you how: http://www.take-a-screenshot.org/ (Links to an external site.). Click on the tab for Mac or Windows at the top, if needed.] Alternatively, click on the arrow in a box at the upper right hand corner of the screen, then you can “Export Image” as a .png file (it appears in your “Downloads” folder) and attach this to your discussion post or drop and drag into a Word file.
Guided Response: Respond to at least three different peers by Day 7. Give specific thoughtful and substantive responses addressing their points and back up your ideas with references. If you notice classmates forgetting to complete part(s) of the discussion, tactfully encourage them to complete the remaining part(s). Be specific. Give a hint, if possible.
Have they answered all the questions pertaining to their problem?
Have they used all the required resources and cited the references correctly?
Do you understand their answers and agree with their conclusions and viewpoints?
What are your arguments against their answers?
