Suppose the administration wanted to determine the number of students age 45+ who purchased a student parking pass. How many students age 45+ should the college survey in order to be 90% confident that the estimated(sample) proportion is within three percentage points of the true population proportion of students aged 45+ who purchased a student parking pass. a) What percentage will you use to determine the sample size? (Round to 2 decimal places) b) What is the critical Z score used to determine the sample size? |(Round to 2 decimal places) c) What is the error bound or margin of error? (Round to 2 decimal places)

Statistics Canada conducts an annual survey to estimate the proportion of Canadians aged 20 - 24 years of age who are smokers. The most recent application of the Canadian Tobacco Monitoring Survey involved a random sample of n=496 Canadians aged 20 to 24 years of age. Each was asked for the smoking status. The number of 20 to 24 year-olds sampled who indicated they were smokers was 333.(a) Compute the sample proportion. Use at least four decimals in your answer.p^= __________ (b) Using your answer in (a), find a 97% confidence interval for pnow, the current proportion of 20 to 24 year old Canadians who are smokers, by Bootstrapping 1000 samples.
