Suppose that a state had a violent crime rate of 543 crimes per 100.000 people. Would that be an unusual number? Explain. O A. No, 543 would not be considered unusual because it is more than two standard deviations from the mean. OB. Yes. 543 would be considered unusual because it is more than two standard deviations from the mean. OC. No, 543 would not be considered unusual because it falls within one standard deviation of the mean OD. Yes, 543 would be considered unusual because it falls within one standard deviation of the mean. d. Suppose that a state had a violent crime rate of 75 crimes per 100,000 people. Would this be considered unusual? Explain. O A. No, 75 would not be considered unusual because it is one standard deviation above the mean. OB. Yes. 75 would be considered unusual because it is more than two standard deviations below the mean. O C. Yes, 75 would be considered unusual because it is one standard deviation below the mean. OD. No, 75 would not be considered unusual because it is not more than two standard deviations from the mean.
