The police department in your city was asked by the mayor’s office to estimate the cost of crime. The police began their study with burglary records, taking a random sample of 500 files since there were too many crime records to calculate statistics for all of the crimes committed. If the average dollar loss in a burglary, for this sample size 500 is $678, with a standard deviation of $560, construct the 95% confidence interval for the true average dollar loss in burglaries rounded to the nearest dollar amount. We can be 95% confident that the upper limit of our interval of dollar loss in crimes committed is $________.

In a random sample of 20 citizens who called the police for service, the mayor’s special adviser on crime found that the average response time was 560 seconds, with a standard deviation of 45 seconds. Construct a confidence interval around your point of estimate and tell the mayor the police response time.
