Consider the confidence interval for μ with known standard deviation Where a1 = a2 = a. Let
Question:
Where a1 = a2 = a. Let a = 0.05 and find the interval for a1 = a2 = a/2 = 0.025. Now find the interval for the case a1 = 0.01 and a2 = 0.04. Which interval is shorter? Is there any advantage to a symmetric confidence interval?
