TV advertising agencies face increasing challenges in reaching audience members because
viewing TV programs via digital streaming is gaining in popularity. A poll reported that 56% of
2342 American adults surveyed said they have watched digitally streamed TV programming on
some type of device. (a) Calculate and interpret a confidence interval at the 99% confidence level
for the proportion of all adult Americans who watched streamed programming up to that point in
time. (Round your answers to three decimal places.) Interpret the resulting interval. We are 99%
confident that this interval does not contain the true population proportion. We are 99%
confident that this interval contains the true population proportion. We are 99% confident that
the true population proportion lies above this interval. We are 99% confident that the true
population proportion lies below this interval. (b) What sample size would be required for the
width of a 99%CI to be at most 0.04 irrespective of the value of p^ ? (Round your answer up to
the nearest integer.).
