\fDescriptive Statistics Std. N Minimum Maximum Mean Deviation Murder Rate per 100K .90 12.30 4.5140 2.41069 Valid N (listwise) 7. The z scores are easily obtained in SPSS and can then be used to answer a wide array of questions. Let's get z scores for the murder rates across states. To do this, go to analyze->descriptive statistics->descriptives. Then, put MurderRt in the variable box and check off the "save standardized values as variables" option. A new variable called "ZMurderRt" will show up at the bottom of variable view: a. Look at the z score for Alabama. What proportion of states are expected to have a higher murder rate? b. Look at the z score for Alaska. What proportion of states are expected to have a lowermurder rate? c. Now compare z scores for Alabama and Alaska. What proportion of states is expected to have a murder rate between that of Alaska and Alabama
