Question 135531
Ans: B
Comment: That is the best answer of the four you must choose from
but that is not a generally accepted statement as to the meaning
of a confidence interval.
The generally accepted meaning is "We are 95% confident that the
population mean lies between 10.5 and 12."
The statement is about confidence, not about probability.  The
population mean either is or is not in that interval; there is
no "probability" of it being there.
