You plan to conduct a survey to find what proportion of the workforce has two or more jobs. You decide on the 90 percent confidence level and state that the estimated proportion must be within 2 percent of the population proportion. A pilot survey reveals that 7 of the 50 sampled hold two or more jobs.
How many in the workforce should be interviewed to meet your requirements?
