Testing hypotheses / statistics – data analytics | DAT565 Data Analysis And Business Analytics | University of Phoenix

Hypothesis testing is used in business to test assumptions and theories. These assumptions are tested against evidence provided by actual, observed data. A statistical hypothesis is a statement about the value of a population parameter that we are interested in. Hypothesis testing is a process followed to arrive at a decision between 2 competing, mutually exclusive, collective exhaustive statements about the parameter’s value.

Consider the following scenario: An industrial seller of grass seeds packages its product in 50-pound bags. A customer has recently filed a complained alleging that the bags are underfilled. A production manager randomly samples a batch and measures the following weights:

Weight, (lbs)

45.6     49.5

47.7     46.7

47.6     48.8

50.5     48.6

50.2     51.5

46.9     50.2

47.8     49.9

49.3     49.8

53.1     49.3

49.5     50.1

To determine whether the bags are indeed being underfilled by the machinery, the manager must conduct a test of mean with a significance level α = 0.05.

In a minimum of 175 words, respond to the following:

  • State appropriate null (Ho) and alternative (H1) hypotheses.
  • What is the critical value if we work with a significant level α = 0.05?
  • What is the decision rule?
  • Calculate the test statistic.
  • Are the bags indeed being underfilled?
  • Should machinery be recalibrated?

Throughout the course, you’ll use the map below to engage important population health concepts. Click on each hot spot to learn more about the population in that area.

This week, you discovered that the focus of healthcare has a growing emphasis on population health. Emphasis on quality improvement and tracking outcomes has led to exploring “why?” Why do some patients have trouble controlling their diabetes? Why do so some pediatric diabetic patients show up in the emergency department with an uncontrolled episode? These questions have led the DNP scholar and other healthcare providers to consider the social determinants of health. This query also requires that consideration be given to “how?” How do healthcare providers improve outcomes for a given population? Explore these questions as they relate to the populations represented on the interactive map below.

Select one of the populations on the map and address the following:  

I select Hialeah, Florida

  • Culture of interest – Hispanic/Latino
  • Population – 224,669
  • Individuals diagnosed with heart disease prior to the study year – 1513
    • age 30 – 40
    • age 35 – 63
    • age 40 – 143
    • age 45 – 189
    • age 50 – 203
    • age 55 – 225
    • age 60 – 299
    • age 65 – 351
  • Individuals newly diagnosed with heart disease in the study year – 409
    • Age 30 – 3
    • Age 40 – 12
    • Age 50 – 41
    • Age 55 – 82
    • Age 60 – 97
    • Age 65 – 174
  • Individuals who died of heart disease in the study year – 531
    • Age 50 – 86
    • Age 55 – 105
    • Age 60 – 130
    • Age 65 – 210
  • Average years of life expectancy reduction due to heart disease – 10

1-Create a culturagram for your selected population. Refer to Week 1, Explore page 2, for guidance in creating a culturagram. You may use the attached template, if you desire.

2-Conduct a search for evidence. Identify one evidence-based intervention to reduce health disparities in the selected population.

3-Consider how the selected intervention addresses at least one of the CLAS standards.

Share your professional experience related to the topic.

Re:Topic 4 DQ 2
The protection of human subject is the utmost necessity in research and must take precedence over all other contributing factors. Children are a vulnerable group and legally, anyone under the age of 18 years must have guardian consent to take part in any research. Furthermore, the IRB “must consider potential benefits, risks, and discomforts of the research of children- to assess justification and inclusion,” (HHS.gov, 2016). Every circumstantial situation must be evaluated including: participant beneficence, potential risks, disease status and society as a whole (HHS.gov, 2016).
Guidelines set forward for minor individuals involved in a protocol must be determined by the IRB from 4 potential categories: (HHS.gov, 2016).
-Research not involving greater than minimal risk to the children.
-Research involving greater than minimal risk but presenting the prospect of direct benefit to the individual child subjects involved in the research.
-Research involving greater than minimal risk and no prospect of direct benefit to the individual child subjects involved in the research, but likely to yield generalizable knowledge about the subject’s disorder or condition.
-Research that the IRB believes does not meet the conditions of 45 CFR 46.404, 46.405, or 46.406,(listed above) but finds that the research presents a reasonable opportunity to further the understanding, prevention, or alleviation of a serious problem affecting the health or welfare of children.
In summary, while the parent or guardian obtains the consent of the child it is important to involve the child (depending on age and mental-status) in decision-making and obtain assent before moving forward.

Original Question: Conducting research projects while ensuring the protection of human subjects is necessary. What are some methods to protect personal rights of someone in one of the groups that is labeled as vulnerable? Justify your rationale
