Transcribed Image Text:1) In a survey on supernatural experiences, 712 of 4019 adult Americans surveyed reported that they had seen or
been with a ghost. Assume that all the required assumptions were met for us to construct a confidence interval
to estimate the proportion of all adult Americans who have seen or been seen with a ghost.
(a) (4) Construct a 90% confidence interval for the proportion of all adult Americans who have seen or been with a
ghost. (Round answers to 3 dec.) put answer into interval below. Show the formula and fill in the pieces to get
your interval.
