As the population ages, there is increasing concern about accident-related injuries to the elderly. An artide reported on an experiment in which the mandmum lean angle the farthest a subject is able to lean and still recover in one step-was determined for both a sample of younger females (21-29 years) and a sample of older females (67-1 years). The following observations are consistent with summary data given in the artide: YF: 29, 36, 33, 27, 28, 32, 31, 34, 32,...

Antipsychotic drugs are widely prescribed for conditions such as schizophrenia and bipolar disease. An article reported on body composition and metabolic changes for individuals who had taken various antipsychotic drugs for short periods of time. (a) The sample of 41 individuals who had taken aripiprazole had a mean change in total cholesterol (mg/dL) of 3.45, and the estimated standard error – - was 3.278. Calculate a confidence interval with confidence level approximately 95% for the true average increase in total...

The data of a major referral hospital showed that most patients with ischemic heart disease (IHD) were black American. Based on this, it was concluded that black Americans are at higher risk of IHD compared to other community groups. How would you describe the conclusion? A. Correct, because risk factors for IHD are more common in black African American. B. Incorrect, because no test of statistical significance has been made C. Incorrect, because prevalence is used instead of incidence D....
