A simple random sample of size n=350 individuals who are currently employed is asked if they work at home at least once per week Of the 350 employed individuals surveyed, 43 responded that they did work at home at least once per week. Construct a 99% confidence interval for the population proportion of employed individuals who work at home at least once per week. The lower bound is (Round to three decimal places as needed.)
