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.t Over a period of months, an adult male patient has taken fifteen blood tests for uric acid. The mean concentration was x = 5.35 ma/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with o = 1.87 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.) 6.29635 4 40365 0 94635 lower limit upper limit margin of error (b) What conditions are necessary for your calculations? (Select all that apply.) O o is unknown O normal distribution of uric acid O n is large O uniform distribution of uric acid 2 o is known (c) Interpret your results in the context of this problem. O we are 5% confident that the true uric acid level for this patient falls within this interval. • We are 95% confident that the true uric acid level for this patient falls within this interval. O The probability that this interval contains the true average uric acid level for this patient is 0.05. O The probability that this interval contains the true average uric acid level for this patient is 0.95. (d) Find the sample size necessary for a 95% confidence level with maximal margin of error E= 1.14 for the mean concentration of uric acid in this patient's blood.
