In 2010, the mean property crime rate(per 100,000)for the 24 states west of a river was3347,the standard deviation was 701,assume the distribution of crime rate is unimodal andsymmetric,complete part A through E.A) What percentage of western states would you expect to have property crime ratesbetween 2646 and 4048?B) What percentage of western states would you expect to have property crime ratesbetween 1945 and 4749?C) If someone guessed that the property crime rate in one state west of Mississippi riverwas 9036, would this number be consistent with the data set?D) The upper bound that represents three standard deviation from mean is?......E) Is 9036 consistent with the data set? (Choose the correct answer)a) Yes, because 9036 falls within two standard deviation of the mean, so it is likely a statewould have this value.b)no, because 9036 falls well above three standard deviations away from the mean and it istherefore unlikely that a state would have this valuec) Yes, because 9036 falls within one standard deviation of the mean so it is likely a statewould have this value.D) No because 9036falls exactly three standard deviations away from the mean, and it istherefore unlikely that a state would have this value.
