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 nine blood tests for uric acid. The mean concentration was x = 5.25 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with o = 1.95 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) What conditions are necessary for your calculations? (Select all that apply.) O normal distribution of uric acid O . is known O uniform distribution of uric acid O n is large O . is unknown (c) Interpret your results in the context of this problem.
