The grade.point averages for 10 students are listed below. Find the range of the data set. 2.0 3.2 1.8 2.9 0.9 4.0 3.3 2.9 3.6 0.8 a. 2.1 b. 2.45 c. 2.8 d. 2.1 e. 3.2

## Step 1<br />The range of a data set is the difference between the highest and lowest values in the set. In this case, the data set consists of the grade point averages of 10 students.<br /><br />## Step 2<br />To find the range, we first identify the highest and lowest values in the data set. The highest value in this data set is 4.0 and the lowest value is 0.8.<br /><br />## Step 3<br />Next, we subtract the lowest value from the highest value to find the range.<br /><br />### **Range = Highest Value - Lowest Value**<br /><br />## Step 4<br />Substitute the highest and lowest values into the formula:<br /><br />### **Range = 4.0 - 0.8**
