1. A recent study by the University Health Research Center, part of the University Medical School, found that 217 of 649 elderly patients admitted for hip fractures experienced a fall in their home the year before the injury. The percentage of falls among elderly people in the United States is 8%. Does the evidence support a hypothesis that falls at home are associated with hip fractures in elderly patients? Construct a 98% confidence interval for the percent of elderly patients with hip fractures who experienced a fall at home in the year before the injury. Interpret your confidence interval. Would your results support a conclusion that there is no difference between the incidence of falls?|
