Part 3
c. If a metropolitan area had a violent crime rate of
378378
crimes per 100,000 people, would this be considered this unusual? Explain.No,
378378
would not be considered unusual because it is more than two standard deviations from the mean.Yes,
378378
would be considered unusual because it falls within one standard deviation of the mean.Yes,
378378
would be considered unusual because it is more than two standard deviations from the mean.No,
378378
would not be considered unusual because it falls within one standard deviation of the mean.Part 4
d. If a metropolitan area had a violent crime rate of
6868
crimes per 100,000 people, would this be considered this unusual? Explain.Yes,
6868
would be considered unusual because it is more than two standard deviations below the mean.No,
6868
would not be considered unusual because it is one standard deviation above the mean.No,
6868
would not be considered unusual because it is not more than two standard deviations from the mean.Yes,
6868
would be considered unusual because it is one standard deviation below the mean.Expert Solution
