The probability that this interval contains the true average uric acid level for this patient is 0.05.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.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 = 1.10 for the mean concentration of uric acid in this patient's blood. (Round your answer up to the nearest whole number.)
