O We are 90% confident that the true proportion of all adult Americans who would say they have seen a ghost falls directly in the middle of this interval.
O We are 90% confident that the mean number of all adult Americans who would say they have seen a ghost falls within this interval.
(f) Would a 99% confidence interval be narrower or wider than the interval calculated in part (e)?
O narrower
O wider
Justify your answer.
The z critical value for higher confidence is -Select- v resulting in a -Select- v confidence interval.
