Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of illness such as gout, leukemia, or lymphoma.† Over a period of months, an adult male patient has taken five blood tests for uric acid. The mean concentration was x = 5.26 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with o = 1.85 mg/dl. (a) Find a 95% confidence interval for the population mean concentration of uric acid in this patient's blood. What is the margin of error? (Round your answers to two decimal places.) lower limit upper limit margin of error (b) Interpret your results in the context of this problem. O We are 5% confident that the true(population) mean uric acid level for this patient falls within this interval. O We are 95% confident that the sample mean uric acid level for this patient falls within this interval. O We are 95% confident that the true(population) mean uric acid level for this patient falls within this interval. O We are 5% confident that the sample mean uric acid level for this patient falls within this interval.
