A random poll of 900 working men found that 8% had taken on a second job to help pay the bills. a) Estimate the true percentage of men that are taking on second jobs by constructing a 95% confidence interval. b) A pundit on a TV news show claimed that only 4% of working men had a second job. Use your confidence interval to test whether his claim is plausible given the poll data. a) Construct a 95% confidence interval for the population proportion. The 95% confidence interval is (. (Round to three decimal places as needed.) b) What does the confidence interval say about the pundit's hypothesis? Because in the interval, we strong evidence that more than % of working men had a second job. (Type integers or decimals. Do not round.)
