Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of ilness such as gout, leukemia, or lymphoma.T Over a period of months, an adult male patient has taken seven blood tests for uric acid. The concentration was x = 5.35 mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with a = 1.77 mg/dl. (a) Find a 95% confidence interval for the population mean concentration 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 o is unknown O normal distribution of uric acid O n is large O o is known O uniform distribution of uric acid (c) Interpret your results in the context of this problem. 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. O we are 95% confident that the true uric acid level for this patient falls within this interval. O we are 5% confident that the true uric acid level for this patient falls within this interval.
