STATISTICS

   A con-over published in JAMA in 2004 examined departed results of other studies on bariatric surgery. Bariatric surgery is manufactured to restore the extent of the stomach in multitudinous ways. It is typically used on merely fleshy patients, and one the transmitted produce of the surgery, gastric bypass has a 1% portraiture (death) admonish caused by the surgery. However, in the studies reporting on the possessions of this surgery on Type II diabetes, 1417 of 1846 diabetic patients cureed altogether from diabetes behind surgery. These patients no longer demand medication enjoy insulin (which is injected into the husk) or pills to succor conduct respect sugar. (a) What is the percentage of patients who cureed from diabetes in 2004? (b) What is the 90%, 95% and 99% Assurance Cessation for the percentage of retrieval from diabetes (2004) grounds? (to impure decimal places for the adaptation - two decimal places if you yield your apology as a percentage). In a con-over released a decade posterior, the percentage of patients who cure from diabetes has increased to 80%. Using Assurance Intervals state whether this is a counting shift from the 2004 grounds.  Use n=2000 (c) What is the percentage of patients who cureed from diabetes in 2014?  What is the enumerate of patients in the exemplification that bear cureed? (d) What is the 90%, 95% and 99% Assurance Cessation for the percentage of retrieval from diabetes (2014) grounds? (to impure decimal places for the adaptation - two decimal places if you yield your apology as a percentage). (e) Based on a similarity of the assurance cessations (parallel merely using the 95% assurance cessation) do you gard that the grounds suggests a counting shift in the enumerate of tribe who bear cureed from Diabetes?  Why? Why not?  If so do you gard the enumerate of tribe who bear cureed from Diabetes in the new con-over is smaller?  Greater?  Why/Why not?  Take a seem at each of the assurance cessations - do they overlap?  What does it balance if the assurance cessations overlap (or don't overlap)? (f) If you had a morbidly fleshy referring-to after a while diabetes what would you count him or her environing bariatric surgery? Explain. Would you commend it? Why/why not?
