master’s degree in Human Resources Management.
I need to do the analysis in spss and present the results. I have attached a draft of my work so far, excel with the data, a file with instructions on what I need to do, and a photo of my model. I need to submit a draft with the results by Saturday and I also need to have an explanation as I will have to present them in 5 minutes.

In this session, we are going through our first statistical test, the Single Sample Z Test (see formula sheet and chart for the Z test attached to the assignment packet).  The class videos, readings, and links, are all designed to help you understand the whole process.  Your homework submissions will also require that your diagram your research study for each problem.  From here on, we will be following this process over and over and over again.  So you will become more comfortable with this process as time goes by.
You will have to answer two questions based on this material.  Question 1 is focused on understanding the effects of sample size on the outcome of the hypothesis test.  Assume a non-directional research question for a two-tail test (see class videos).  Question 2 is based on a real research study.  Watch for the research question to determine if the research question is a directional (one-tail) or non-directional (two-tail) question.

Points will be awarded for correct grammar, punctuation, spelling, and coherence/clarity of writing.
Choose a health subject that you want to study for this report. You will need to find the data and
enter it into SPSS. The Centers for Disease Control website (www.cdc.gov) has some data that
might be interesting to you. Once on the site, you can search for “Summary of Notifiable
Infectious Diseases and Conditions” which is published on an annual basis. You may want to
view the data for a particular Health Issue over a period of years, such as by comparing 2011’s
report with 2014’s report.
Here is a link to CDC annual reports.
https://www.cdc.gov/mmwr/mmwr_nd/index.html
The California Health Information
Survey https://healthpolicy.ucla.edu/Pages/AskCHIS.aspx also has available data for
analysis.
You will need to create an account to access the data set if you haven’t already created
one.
For this report, you will:
• Conduct a Significance Test on that data using SPSS.
• Create a Report using Microsoft Word which will contain the following
four Sections: “Purpose”, “Methods”, “Analysis and Results”, and “Conclusion”.
Purpose

Message: Social responsibility is a framework of ethics in which an individual collaborates and works with other organizations and individuals for the betterment of the community. There are numerous ways in which an organization can exhibit social responsibility; for instance, by promoting volunteerism, facilitating donations, employing ethical employment practices, and implementing environmental improvements. It introduces the subjective obligation that entails maintaining a delicate equilibrium between one’s ecosystem and the economy, as well as the potential compromises that may be made between economic progress and societal and environmental wellbeing. This transcends business organizations and affects all individuals whose actions influence the environment.
Solve the following questions using Excel QM. (2×4 = 8 marks)
1.Helping others through blood donation is a form of social solidarity or social responsibility. The blood donors cite a sense of social responsibility as their reason for donating blood, and as a result, the communities value and reward this activity. The following table shows the number of blood donors in a university from 2011–2023. Develop a 3-year moving average forecast and obtain the related statistical measures using excel QM. year

Please see the attached. 
The research department of an appliance
manufacturing firm has developed a new bimetallic thermal sensor for its
toaster. The new bimetallic thermal sensor can sense the temperature of the
bread and move the lever arm to activate the switch. The research department
claims that the new bimetallic thermal sensor will reduce appliance returns
under the one-year full warranty by 2%-6%. To determine if the claim can be
supported, the testing department selects a group of the toasters manufactured
with the new bimetallic thermal sensor and a group with the old thermal sensor
and subjects them to a normal year’s worth of wear. Out of 250 toasters tested
with the new bimetallic thermal sensor, 8 would have been returned. Seventeen
would have been returned out of the 250 toasters with the old thermal sensor.
As the manager of the appliance manufacturing process, use a statistical
procedure to verify or refute the research department’s claim.

Initial Post Instructions 
Present two different types of data, or variables, used in the health field. Examples could be   blood pressure, temperature, pH, pain rating scales, pulse oximetry, % hematocrit, minute respiration, gender, age, ethnicity, etc.
Classify each of your variables as qualitative or quantitative and explain why they fall into the category that you chose.
Also, classify each of the variables as to their level of measurement–nominal, ordinal, interval or ratio–and justify your    classifications.
Which type of sampling could you use to gather your data? (stratified,             cluster, systematic, and convenience sampling)
REPOND TO THIS POST
Hello class!
Two types of variables that are used in the healthcare field are..
1: Blood Pressure
2: Gender
Classifying Each Variable:
1: Blood pressure is a quantitative variable in this situation because it falls under numerical data. A patient’s blood pressure can be taken by using numerical values such as millimeters of mercury in the blood.
2: Gender is a qualitative variable in this situation due to how it represents categories instead of numerical values the way that the blood pressure does. Gender can be classified as either male or female. 
Level of Measurement:
1: Blood pressure is at the ratio level because it has a meaningful zero point.
2: Gender is at the nominal level because it represents categories without an inherent order or numerical significance, such as a human. 
Sampling Method:
Stratified sampling can be used to gather the correct facts on this data. This requires dividing the population  and randomly selecting participants from each stratum to provide their representation from various subgroups.
