Sam computed a 90% confidence interval for ? from a specific random sample of size n. He claims that at the 90% confidence level, his confidence interval contains ?. Is this claim correct? Explain. No. The proportion of all confidence intervals based on random samples of size n that contain ? is 0.10.Yes. 90% of all confidence intervals will contain ?.    No. The probability that this interval contains ? is either 0 or 1.Yes. The proportion of all confidence intervals based on random samples of size n that contain ? is 0.90.
