survey on supernatural experiences, surveye they ghost. (a) What assumption must be made in order for it to be appropriate to use the formula of this section to construct a confidence interval to estimate the proportion of all adult Americans who have seen or been with a ghost? ◇ We need to assume that the 4003 people were surveyed at a supernatural convention. ○ We need to assume that there are only 712 adult Americans. ◇ We need to assume that the 712 people are the only Americans who had seen or been with a ghost. We need to assume that the 4003 people formed a random sample of adult Americans. (b) Construct a 90% confidence interval for the proportion of all adult Americans who have seen or been with a ghost. (Round your answers to three decimal places.) ( Interpret the interval. ◇ We are confident that the proportion of all adult Americans who have seen or been with a ghost is within this interval 90% of the time. We are 90% confident that the proportion who have seen or been with a ghost is within this interval. We are 90% confident that the proportion of all adult Americans who have seen or been with a ghost is within this interval.
