Bowie State University Statistics Null and Alternative Hypothesis Presentation I need help with my homework. The homework is PowerPoint presentation. I’ll attach the files need for it and if you have any questions please ask 5. Based on your selected topic, evaluate the following:
o Find the best point estimate of the population mean.
o Construct a 95% confidence interval for the population
mean. Assume that your data is normally distributed
and o is unknown.
• Please show your work for the construction of this
confidence interval and be sure to use the
Equation Editor to format your equations.
o Write a statement that correctly interprets the
confidence interval in context of your selected topic.
6. Based on your selected topic, evaluate the following:
o Find the best point estimate of the population mean.
o Construct a 99% confidence interval for the population
mean. Assume that your data is normally distributed
and o is unknown.
• Please show your work for the construction of this
confidence interval and be sure to use the
Equation Editor to format your equations.
o Write a statement that correctly interprets the
confidence interval in context of your selected topic.
7. Compare and contrast your findings for the 95% and 99%
confidence interval.
o Did you notice any changes in your interval estimate?
Explain.
o What conclusion(s) can be drawn about your interval
estimates when the confidence level is increased?
Explain.
8. Discuss the process for hypothesis testing.
o Discuss the 8 steps of hypothesis testing?
o When performing the 8 steps for hypothesis testing,
which method do you prefer; P-Value method or
Critical Value method? Why?
9. Perform the hypothesis test.
o If you selected Option 1:
• Original Claim: The average salary for all jobs in
Georgia is less than $65,000.
• Test the claim using a = 0.05 and assume your
is normally distributed and o is unknown.
9. Perform the hypothesis test.
o If you selected Option 1:
• Original Claim: The average salary for all jobs in
Georgia is less than $65,000.
• Test the claim using a = 0.05 and assume your data
is normally distributed and o is unknown.
o If you selected Option 2:
• Original Claim: The average age of all patients
admitted to the hospital with infectious diseases is
less than 65 years of age.
• Test the claim using a = 0.05 and assume your data
is normally distributed and o is unknown.
o Based on your selected topic, answer the following:
1. Write the null and alternative hypothesis
symbolically and identify which hypothesis is the
claim.
2. Is the test two-tailed, left-tailed, or right-tailed?
Explain.
3. Which test statistic will you use for your
hypothesis test; z-test or t-test? Explain.
4. What is the value of the test-statistic? What is the
P-value? What is the critical value?
5. 5.) What is your decision; reject the null or do not
reject the null?
a. Explain why you made your decision
including the results for your p-value and
the critical value.
6. State the final conclusion in non-technical terms.
10. Conclusion
o Recap your ideas by summarizing the information
presented in context of your chosen scenario.
Week 9 Post (300+ Words): In hypothesis testing we set
alpha, the significance level, which limits the likelihood of
making a Type 1 error if the null hypothesis were true. When
does a type 2 error occur? Give a real world example of a
decision and explain what the null hypothesis, alternative
hypothesis, type 1 and type 2 errors would be – which would
be worse in this case: making a type 1 error or making a type 2
error?

As a healthcare professional, you will work to improve and
maintain the health of individuals, families, and communities in
various settings. Basic statistical analysis can be used to gain an
understanding of current problems. Understanding the current
situation is the first step in discovering where an opportunity for
improvement exists. This project will assist you in applying
basic statistical principles to a fictional scenario in order to
impact the health and wellbeing of the clients being served.
You are currently working at Grady Memorial Hospital in the
Infectious Diseases Unit. Over the past few days, you have
noticed an increase in patients admitted with a particular
infectious disease. You believe that the ages of these patients
play a critical role in the method used to treat the patients. You
decide to speak to your manager and together you work to use
statistical analysis to look more closely at the ages of these
patients. You do some research and put together a spreadsheet
of the data that contains the following information:
• Client number
• Infection Disease Status
• Age of the patient
You need the preliminary findings immediately so that you can
start treating these patients. So let’s get to work!!!!
The data set consists of 60 patients that have the infectious
disease with ages ranging from 35 years of age to 76 years of
age for Grady Memorial Hospital.
