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 54% of 2341 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. (Rou your answers to three decimal places.) Interpret the resulting interval. O We are 99% confident that the true population proportion lies above this interval. O We are 99% confident that this interval contains the true population proportion. O We are 99% confident that this interval does not contain the true population proportion. O 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 0.03 irrespective of the value of p? (Round your answer up to the nearest integer.)

According to recent data by the American Marketing Association, 76.5%of people in the 18-24 age group used social media in 2017. You want to find out what the social media proportion is among your classmates who are all between 18 and 24 years old. Suppose you obtain a random sample of 229 students and find that 202 students in this sample are active social media users. Complete parts a through c below. a. Construct a 99% confidence interval to estimate the actual proportion of social media users. A 99% confidence interval to estimate the actual proportion has a lower limit of------ and an upper limit of------- (Round to three decimal places as needed.) b. What is the margin of error for this sample? c. Is there evidence that this proportion matches that of the overall population based on the sample?
Data are used either to test a hypothesis or to construct a confidence interval, but not both. Explain.
A survey asked, "How many tattoos do you currently have on your body?" Of the 1233 males surveyed, 183 responded that they had at least one tattoo. Of the 1042 females surveyed, 139 responded that they had at least one tattoo. Construct a 95% confidence interval to judge whether the proportion of males that have at least one tattoo differs significantly from the proportion of females that have at least one tattoo. Interpret the interval. C Let p₁ represent the proportion of males with tattoos and p2 represent the proportion of females with tattoos. Find the 95% confidence interval for p₁ -P2- The lower bound is The upper bound is (Round to three decimal places as needed.)
