The test scores of the students in four classes are summarized below. Answer the questions about them. Class A: The mean score is 95 and the range of scores is 41 . Class B: The mean score is 100 and the range of scores is 36 . Class C: The mean score is 101 and the range of scores is 37 . Class D: The mean score is 99 and the range of scores is 35 . (a) Based on the information above, which class has the highest scores on average? (b) Based on the information above, whici class's scores have the least variability? O Class A Class B

**Step 1: Determine the class with the highest average** - The mean scores for the classes are: - Class A: \(95\) - Class B: \(100\) - Class C: \(101\) - Class D: \(99\) - The highest mean is \(101\) for Class C. Thus, the answer for part (a) is: **Class C**. **Step 2: Determine the class with the least variability** - The variability in this context is measured by the range of the scores. - The ranges for the classes are: - Class A: \(41\) - Class B: \(36\) - Class C: \(37\) - Class D: \(35\) - The smallest range is \(35\) for Class D, indicating the least variability. Thus, the answer for part (b) is: **Class D**.
