Step 1
We do this by dividing the number of visitors (61) by the total number of participants in the survey (320). Sample proportion (p̂) = 61 / 320 = 0.190625 Show more…

A survey of the audience at a popular comedian's show at the Sydney Opera House has been conducted and found that 69 of the 287 members of the audience who participated in the survey are visitors to Sydney. (a) Calculate a 90% confidence interval for the proportion of audience members at the comedian's show who are visitors to Sydney. Present your work. (b) Interpret the confidence interval. (c) To conduct a new follow-up study that would provide 95% confidence that the point estimate is correct to within ± 0.04 of the population proportion, how large a sample size is required? (d) To conduct a a new follow-up study that would provide 99% confidence that the point estimate is correct to within ± 0.04 of the population proportion, how large a sample size is required?

A rock and roll music promoter is deciding whether to book a new band for a concert. The band's music appeals mostly to teenagers. There are 400,000 teenagers in the market served by the concert venue. The promoter decides to do a survey to try to estimate the proportion of teenagers who will attend the concert. How large a sample should be taken in order to estimate the proportion to within .02 with 99% confidence? Suppose the promoter takes a sample of size 600 and 508 say they will not attend. What is the 95% confidence interval for the proportion of teenagers in this market who will attend the concert. What is the 95% confidence interval for the number of teenagers who will attend the concert.

A study showed that in a sample of 60 people, 18 had visited Disneyland. In another sample of 80 people, 20 had visited Disney World. Disneyland vs Disney World Are the proportions of people who visited each park different? Use α = 0.01 Construct a 98% confidence interval for the difference in proportion of people attending the two parks. BONUS: Construct a 99% confidence interval for Question #8 and interpret the interval in the context of the question:
