Question
A simple CI
Let θ be an unknown parameter, and let X be uniform on the interval [θ−0.5,θ+0.5].
Is [X−2,X+2] an 80% confidence interval?
unanswered
I form a confidence interval of the form [X−a,X+a]. What is the narrowest confidence interval of this type (i.e., what is the smallest possible choice of
a) if I want to have an 80% confidence interval?
