Burglary In 2014, the mean burglary rate (per 1000 houses) for all cities in a state was 250; the standard deviation was 25. Assume the distribution of burglary rates is approximately unimodal and symmetric.
a. Approximately what percentage of cities would you expect to have burglary rates between 225 and 275?
b. Approximately what percentage of cities would you expect to have burglary rates between 200 and 300?
c. If someone guessed that the burglary rate in one of the cities was 0, would you agree that that number was consistent with this data set?
