Thinking of the many variables tracked by hospitals and doctors' offices, confidence
intervals could be created for population parameters (such as means or proportions) that
were calculated from many of them. Choose a topic of study that is tracked (or you would
like to see tracked) from your place of work. Discuss the variable and parameter (mean or
proportion) you chose, and explain why you would these to create an interval that captures
the true value of the parameter of patients with 95% confidence.
Consider the following:
How would changing the confidence interval to 90% or 99% affect the study? Which of
these values (90%, 95%, or 99%) would best suit the confidence level according to the type
of study chosen? How might the study findings be presented to those in charge in an
attempt to affect change at the workplace?

Hi Prof. B and class,
Hi Prof. B and class,
You forewarned us about this topic being challenging, well it is. Holmes (2018) defines
confidence interval as another type of estimate but, instead of being just one number, it is an
interval of numbers. The interval of numbers is a range of values calculated from a given set of
sample data, it is likely to include the unknown population parameter (p. 334). In all hindsight,
this topic got me thinking. I’m not sure how this is tracked in my facility, but we’ve had more
than a few instances of UTI’s with several of our residents and I work in a relatively small skilled
nursing facility (SNF). I would like to see how it’s tracked and what are the criteria used to
prescribe antibiotics, what can we do to prevent recurring UTI's. We’ve had a few residents that
have been sent out to the ER due signs and symptoms, tachycardia, dysuria, change in mental
status, confusion, elevated temp, among some of the symptoms exhibited; one of these residents
has colonized bacteria despite the use of IV abt. A few others have been treated with oral
antibiotics. One of these residents has been prescribed the infectious disease physician antibiotics
indefinitely.
