Stats exam is less than a week away and while looking through a past paper I found a question that seems very poorly written.
"Given that u = 1000, state the probability that a 98% confidence interval for u will not contain 1000." (I put u for the Greek Mu (mean))
How can a confidence interval not contain its own mean? What is the question attempting to ask?
Thank you

Question 5c
To me it does not appear to be connected to any of the others in Q5
