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 that 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 use 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?

Hello Instructor and class
I am interested in studying the impact of brisk walking on high blood pressure. I have been dealing with hypertension cases for over a time now, and I would like to establish alternative ways to manage it. Brisk walking (100 steps per minute) can lower your systolic blood pressure 6 millimeters of mercury (mm Hg), which represent the parameter of the population (Prabakaran, Vijayalakshmi &VenkataRao, 2013).
A 95% CI implies that if I would sample numerous times from the same population and calculate a range of estimates for these samples, 95% of the intervals within the lower and upper limits of this range will include……………..
