Bowie State University Constructive Confidence Intervals Questions I need help with my homework. The files will be attached if you have any questions please let me know. 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
you can
• Age of the patient
You need the preliminary findings immediately so that
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.
1. Discuss the importance of constructing confidence intervals
for the population mean.
o What are confidence intervals?
o What is a point estimate?
o What is the best point estimate for the population
mean? Explain.
o Why do we need confidence intervals?
2. Find the best point estimate of the population mean.
3. Construct two confidence intervals for the population
mean: a 95% confidence interval and a 99% confidence
interval. Assume that your data is normally distributed
and the population standard deviation is unknown.
o Please show your work for the construction of
these confidence intervals and be sure to format
your equations to fit the appropriate form (may
need editing here).
4. Write a paragraph that correctly interprets the confidence
intervals in context of your selected topic.
5. Compare and contrast your findings for the 95% and 99%
confidence intervals.
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.2
Give an example of an interval estimate of an average or
proportion you may use in your daily life. For instance, you
may say that you are pretty sure your average commute time
is between 25-30 minutes, or you are fairly confident that
between 60-65% of the population love dogs. Collect some
data to see how well your intuition is working. First, does your
sample data meet all assumptions necessary to construct the
confidence interval of the type you need? Even if it doesn’t,
construct and interpret the confidence interval.
