A chain of music stores is interested in the proportion of households owning a piano. They conduct a random survey using inverse sampling; their interviewers pool households at random until finding m = 19 households with pianos. In their latest community survey, they needed to conduct n = 359 interviews before finding the target number of piano owners. What is variance of their estimate of the proportion of households owning a piano? (calculate to 4 decimal places) Moving to another question will save this response.
