At a recent meeting at the American College of Asthma, Allergy, and Immunology, researchers reported that allergy vaccinations are effective in treating sinusitis (inflammation of the membrane lining the facial sinuses) in individuals predisposed to allergies. Specifically, the researchers reported that 98% of individuals predisposed to allergies find relief from their sinusitis after allergy vaccinations. Suppose that this number is accurate and that 130 individuals predisposed to allergies are chosen at random and given allergy vaccinations. Answer the following. (If necessary, consult a list of formulas.) (a) Estimate the number of individuals in the random sample who do not find relief from their sinusitis by giving the mean of the relevant distribution (that is, the expectation of the relevant random variable). Do not round your response. 0 (b) Quantify the uncertainty of your estimate by giving the standard deviation of the distribution. Round your response to at least three decimal places. X

A study published in JAMA in 2004 examined past results of other studies on bariatric surgery.  Bariatric surgery is done to replace the size of the stomach in various ways.  It is typically used on only obese patients,  and one the traditional form of the surgery,  gastric bypass has a 1% mortality (death) rate caused by surgery.  However,  in the studies reporting on the effects of the surgery on Type ll diabetes,  1417 of 1846 diabetic patients recovered completely from diabetes after surgery.  These patients no longer need medication like insulin (which is injected into the skin) or pills to help manage blood sugar.  In a study released a decade later,  the percentage of patients who recover from diabetes has increased 80%. Using confidence intervals determine whether this is a significant change from the 2004 data. Use n=2000

A new drug to treat psoriasis has been developed and is in clinical testing. Assume that those individuals given the drug are examined before receiving the treatment and then again after receiving the treatment to determine if there was a change in their symptom status. If the initial results showed that 2.0% of individuals entered the study in remission, 77.0% of individuals entered the study with mild symptoms, 16.0% of individuals entered the study with moderate symptoms, and 5.0% entered the study with severe symptoms calculate and interpret a chi-squared test to determine if the drug was effective treating psoriasis given the information below from the final examination.   A. We reject H0 because 6628.08 is greater than 11.07. We have statistically significant evidence at the alpha equals .05 level to show that the distribution of the severity of psoriasis cases at the end of the clinical trial for the sample is different from the distribution of the severity of psoriasis…

A study published in JAMA in 2004 examined past results of other studies on bariatric surgery.  Bariatric surgery is done to replace the size of the stomach in various ways.  It is typically used on only obese patients,  and one the traditional form of the surgery,  gastric bypass has a 1% mortality (death) rate caused by surgery.  However,  in the studies reporting on the effects of the surgery on Type ll diabetes,  1417 of 1846 diabetic patients recovered completely from diabetes after surgery.  These patients no longer need medication like insulin (which is injected into the skin) or pills to help manage blood sugar.   If you had a morbidly obese relative with diabetes what would you tell him or her about bariatric surgery? Explain. Would you recovered it? Why/ why not?

The fecal occult blood test, widely used both in physicians’ offices and at home to screen patients for colon and rectal cancer, examines a patient’s stool sample for blood, a condition indicating that cancer may be present. A recent study funded by the National Cancer Institute found that of 15,000 people tested on an annual basis, 10% were found to have blood in their stools. These 10% underwent further testing, including colonoscopy, the insertion of an optical-fiber tube through the rectum in order to inspect the colon and rectum visually for direct indications of cancer. Only 2.5% of those having colonoscopy actually had cancer. Additional information in the study suggests that, of the patients who were tested, approximately 5 out of 1,000 tested negative (no blood in the stool) but eventually did develop cancer. Create a probability table that shows the relationship between blood in a stool sample and colorectal cancer. Calculate P(Cancer|Blood) and P(Cancer|No Blood). The study…
