Over a period of months an adult male patient has taken eight blood tests for uric acid. The mean concentration iswas x with a line over it =5.35 mg/dl. The distribution of uric acid for the health adult male can be assumed to be normal with the standard deviation of 1.85 mgdl.
a. Find a 95% confidence interval for the population mean concentration of uric acid in this patients blood. What is the margin of error?
b. What conditions are necessary for the calculations?
c. Give a brief interpretation of your results in context of this problem.
d. Find the sample size necessary for a 95% confidence level with the maximal error of estimate E=1.10 for the mean concentration of uric acid in the patients blood.
