) Overproduction of uric acid in the body can be an indication of cell breakdown. This may be an advance indication of an illness such as gout, leukemia, or lymphoma. Over a period of months, an adult male patient has taken eight blood tests for uric acid. His mean concentration was mg/dl. The distribution of uric acid in healthy adult males can be assumed to be normal, with รณ = 1.85. You are interested in a 99% confidence interval for the mean concentration of uric acid for this patient.




___(a) Write down the proper formula to use
________________________________(b) What is the value of or for your interval
_____________________________ (c) What is the value of the margin of error for your interval
__________________________________________ (d) Give the 99% confidence interva
(e) Interpret your interval in the context of the problem.

    Formula:

    CI99 = mean + or - 2.58(sd/√n)

    ...where + or - 2.58 represents the 99% confidence interval using a z-table; sd = standard deviation; n = sample size.

    I'll let you take it from here.
