In order to determine how many teachers would be in favor of a 4-day school schedule (with the
5" day being a day for grading, lesson planning, etc.), a local school district is going to sample their teachers to get an estimate of the true proportion. At the last minute, they decide to use a 95% confidence level instead of an original 98% confidence level. Which of the following statements about this change is true?
(A) The 95% confidence interval would be wider, and therefore less precise.
(B) The 95% confidence interval would be wider, and therefore more precise.
(C) The 95% confidence interval would be narrower, and therefore less precise.
(D) The 95% confidence interval would be narrower, and therefore more precise.
(E) No statement can be made about the width and precision of the confidence interval.
