You are interested in interviewing people who own both a cat and a dog. The estimated incidence rate in the population is 17%. You expect a survey completion rate of 45%. (1) What final sample size would be required to obtain a statistical estimate of a parameter with an expected proportion of 50% within +/- 3% with 95% confidence? (2) What initial sample size (e.g., how many invites) is required to obtain the necessary final sample size for analysis?
