AUMC A Situation where Root Cause Analysis Could be Used Discussion
We know that quantitative analysis approach includes a high level overview of the importance of identifying the problem, developing a model, acquiring input data, developing a solution, testing the solution, analyzing results, and implementation through the DMAIC approach we covered in Module 1. Describe a specific situation where root cause analysis could be conducted. Which tool would be most effective and why?

MCAD Hypothesis Test for a Difference in Two Population Means Worksheet
Learn by DoingIn this activity you will learn to use StatCrunch to perform a two-sample t-test.Some features of this activity may not work well on a cell phone or
tablet. We highly recommend that you complete this activity on a
computer.Here are the directions and grading rubric for the discussion board exercises. A list of StatCrunch directions is provided at the bottom of this page.ContextDo undergraduates sleep less than graduate students?A student conducted a study of sleep habits at a large state
university. His hypothesis is that undergraduates will party more and
sleep less than graduate students. He surveyed random samples of 75
undergraduate students and 50 graduate students. Subjects reported the
hours they sleep in a typical night.For this hypothesis test, he defined the population means as follows:
μ
1
is the mean number of hours undergraduate students sleep in a typical night.
μ
2
is the mean number of hours graduate students sleep in a typical night.VariablesHours: typical number of hours a student sleeps each night Program: undergraduate or graduate Program is the explanatory variable, and the data is categorical. Hours is the response variable, and the data is quantitative.DataTwo sample T hypothesis test:μ1 : Mean of undergraduateμ2 : Mean of graduateμ1 - μ2 : Difference between two meansH0 : μ1 - μ2 = 0HA : μ1 - μ2 < 0(without pooled variances)Hypothesis test results:

PromptState the null and alternative hypotheses. Include a clear description of the populations and the variable.Explain why we can safely use the two-sample T-test in this case.Use StatCrunch to carry out the test. Copy and paste the content of in the StatCrunch output window (text and the table) in your initial post. State a conclusion in the context of this problem.ANSWER(S): (hint)Since we want to check whether the data supports the claim that
undergraduate students sleep less, on average, than graduate students,
we are testing:

We can safely use the two-sample T-test in this case since:
Both samples are random, and therefore independent.The sample sizes (75 and 50) are quite large, and therefore we can
proceed regardless of whether the populations are normal or not.
T = -1.23; P-value = 0.111Here is the StatCrunch output depicting these values.Two sample T hypothesis test:
μ

The P-value (0.111) is greater than 0.05. This indicates that
the observed data is not unusual if undergraduate and graduate students,
on average, have the same mean for sleep hours. Therefore, the data do
not provide evidence to reject
H
0
. So we cannot conclude that undergraduate students sleep less, on average, than graduate students.

Assignment 2: Multiple Regression in Practice
Assignment 2: Multiple Regression in PracticeFor this Assignment, you will continue your practice as a critical consumer of research. You will critically evaluate a scholarly article related to multiple regression.To prepare for this Assignment:Use the Course Guide and Assignment Help found in this week’s Learning Resources and search for a quantitative article that includes multiple regression testing.For this Assignment:Write a 2- to 3-page critique of the article. In your critique, include responses to the following:Why did the authors use multiple regression?Do you think it’s the most appropriate choice? Why or why not?Did the authors display the data?Do the results stand alone? Why or why not?Use proper APA format, citations, and referencing.

PUBH8545 Medical Exploration Screening for Cardiovascular Disease Report
In many different situations, you may be exposed to information that requires further analysis; this may be true as you receive reports, read a journal, or prepare for a presentation. What is certain is that you should always approach results in a critical but unbiased way, and be prepared to address any potential weaknesses in the reported data.For this Discussion, you will evaluate recommendations made based on the results of a study from a given scenario.To prepare:Select one of the following scenarios:Scenario 1: A sample of 5,000 swimmers and 5,000 runners were screened for cardiovascular disease (CVD). The study found that the rate of CVD is 33.3% in swimmers and 30.9% in runners, with the p-value of <0.05. A public campaign is recommended to promote running instead of swimming activities.Scenario 2: A study of 1,000 married women was conducted concerning pre-marital birth and the success of the subsequent marriages. The study reported that less educated women were 30% more likely to have children before marriage than highly educated women. In addition, 40% of the African-American women in the study had children before marriage. The study concluded that marriage counseling should be provided to less educated women and to African-American women.Post an evaluation of the recommendation from your scenario. Include the following in your post:The scenario number you selectedYour evaluation of whether the recommendations are overstated or understated based on the results described in the scenario (justify your response)Your suggestion of two methods for addressing and correcting those errorsSupport your post with the Learning Resources and current literature. Use APA formatting for your Discussion and to cite your resources.Referenceshttps://class.waldenu.edu/bbcswebdav/institution/USW1/201950_27/PH_PUBH/PUBH_8545_WC/readings/USW1_PUBH_8545_Week10_wantedValidAndMeaningfulData.pdfFullerton, S.
