Chamberlain Chapter 8 Week 6 Confidence Intervals in Clinical Studies Discussion
Required ResourcesRead/review the following resources for this activity:Textbook: Chapter 8LessonMinimum of 1 scholarly sourceIn your reference for this assignment, be sure to include both your text/class materials AND your outside reading(s).Confidence IntervalsIn everyday terms, a confidence interval is the range of values around a sample statistic (such as mean or proportion) within which clinicians can expect to get the same results if they repeat the study protocol or intervention, including measuring the same outcomes the same ways. As you ask yourself, "Will I get the same results if I use this research?", you must address the precision of study findings, which is determined by the Confidence Interval. If the CI around the sample statistic is narrow, you can be confident you will get close to the same results if you implement the same research in your practice.Consider the following example. Suppose that you did a systematic review of studies on the effect of tai chi exercise on sleep quality, and you found that tai chi affected sleep quality in older people. If, according to your study, you found the lower boundary of the CI to be .49, the study statistic to be 0.87, and the upper boundary to be 1.25, this would mean that each end limit is 0.38 from the sample statistic, which is a relatively narrow CI.(UB + LB)/2 = Statistic [(1.25 + .49)/2 = .87]Keep in mind that a mean difference of 0 indicates there is no difference; this CI does not contain 0. Therefore, the sample statistic is statistically significant and unlikely to occur by chance.Because this was a systematic review, and tai chi exercise has been established from the studies you assessed as helping people sleep, based on the sample statistics and the CI, clinicians could now use your study and confidently include tai chi exercises among possible recommendations for patients who have difficulty sleeping.Now you can apply your knowledge of CIs to create your own studies and make wise decisions about whether to base your patient care on a particular research finding.Initial Post InstructionsThinking 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?

Question 80 A
pharmaceutical company produces the drug NasaMist from four chemicals.
Today, the company must produce 1000 pounds of the drug. The three
active ingredients in NasaMist are A, B, and C. By weight, at least 8%
of NasaMist must consist of A, at least 4% of B, and at least 2% of C.
The cost per pound of each chemical and the amount of each active
ingredient in one pound of each chemical are given in the file
P14_80.xlsx. It is necessary that at least 100 pounds of chemical 2 and
at least 450 pounds of chemical 3 be used. Determine the cheapest way of producing today’s batch of NasaMist.Use
SolverTable to see how much the percentage of requirement of A is
really costing the company. Let the percentage required vary from 6% to
12%.q86The government is auctioning off oil
leases at two sites: 1 and 2. At each site 10,000 acres of land are to
be auctioned. Cliff Ewing, Blake Barnes, and Alexis Pickens are bidding
for the oil. Government rules state that no bidder can receive more than
40% of the land being auctioned. Cliff has bid $10,000 per acre for
site 1 land and $20,000 per acre for site 2 land. Blake has bid $9000
per acre for site 1 land and $22,000 per acre for site 2 land. Alexis
has bid $11,000 per acre for site 1 land and $19,000 per acre for site 2
land. Determine how to maximize the government’s revenue.Use
SolverTable to see how changes in the government’s rule on 40% of all
land being auctioned affect the optimal revenue. Why can the optimal
revenue not decrease if this percentage required increases? Why can the
optimal revenue not increase if this percentage required decreases?
