apply the concepts of sampling distributions and confidence intervals to make management decisions

Develop a summary in the text boxes including the following calculations and using the information to determine whether the new billing system has reduced the mean bill payment time:

  • Assuming the standard deviation of the payment times for all payments is 4.2 days, construct a 95% confidence interval estimate to determine whether the new billing system was effective. State the interpretation of 95% confidence interval and state whether or not the billing system was effective.
  • Using the 95% confidence interval, can we be 95% confident that µ ≤ 19.5 days?
  • Using the 99% confidence interval, can we be 99% confident that µ ≤ 19.5 days?
  • If the population mean payment time is 19.5 days, what is the probability of observing a sample mean payment time of 65 invoices less than or equal to 18.1077 days?

assessment tool or diagnostic test

 
 
Case Study #1
“Patient JB, 39 yo Caucasian female, is seen by her care provider for a complaint of productive cough, weakness, and “I just havenâ€t felt good for the past 2 weeks.” The care provider completes an assessment of listening to her lungs by having her take 2 deep breaths and informs her that her lungs are clear and to take OTC cough medication and hydrate well. The next day, JB feels worse and visits a different care provider who at this time, assesses her head, eyes, ears, nose, throat, auscultates her heart sounds and hears a murmur (which she did not know she had), auscultates her lungs by having her to take 4 deep breaths, performs percussion techniques, and tells her there is fluid on her lungs, examines her lower extremities and notices that there is bilateral  2+ pitting edema, and lastly, reviews her vital signs and tells her that her heart rate is 120, respirations are 22, and she has a temp of 101.
Questions:
1.)   Is the health history about the patientâ€s complaint thorough?
2.)   Which providerâ€s examination would provide the patient with an accurate diagnosis and treatment plan?
