Overproduction of uric acid in the body can be an indication ofcell breakdown. This may be an advance indication of illness suchas gout, leukemia, or lymphoma.†Over a period of months, an adultmale patient has taken eleven blood tests for uric acid. The meanconcentration was x = 5.35 mg/dl. The distribution of uric acid inhealthy adult males can be assumed to be normal, with σ = 1.89mg/dl. (a) Find a 95% confidence interval for the population meanconcentration of uric acid in this patient's blood. What is themargin of error? (Round your answers to two decimal places.)
lower limit
upper limit

(b) Find the sample size necessary for a 95% confidence levelwith maximal margin of error E = 1.10 for the meanconcentration of uric acid in this patient's blood. (Round youranswer up to the nearest whole number.)
