Chen was planning to conduct a mail survey with Florida female farmers to estimate the gendered division of household labor. She obtained the mailing addresses of farmers operating in the State of Florida from the Florida Department of Agriculture and Consumer Services. There are 4000 farmers on the list (note that not all farmers are willing to share their mail addresses) and among them, 1500 farmers are female. A. What is the incident rate? (0.5 pts) What is the response rate if 200 female farmers returned the completed survey? (0.5 pts) B. What is the margin of error in this sample? (1 point) C. In order to have a 5% margin of error, what would be the minimum sample size? (1 point) What would you recommend her to do to increase the sample size? (1 point)
