The mean caffeine content μ of a certain energy drink is under examination. A measure taken on a random sample of size n = 16 yieldsx̄ = 2.4 g/l. (a) Assuming that the standard deviation is known to be σ = 0.3, find the 95 confidence interval for μ. (b) If that the standard deviation is unknown but the sample standard deviation is s = 0.3, find the 95 confidence interval for μ.
