Answer

Explanation:

Step1: Find the range

Range = Max - Min. In the set {20, 15, 50, 85, 75, 60}, Max = 85 and Min = 15. So, Range = 85 - 15 = 70.

Step2: Find the mid - range

Mid - range=$\frac{Max + Min}{2}$. Substituting Max = 85 and Min = 15, we get Mid - range=$\frac{85 + 15}{2}=\frac{100}{2}=50$.

Answer:

The range is 70 and the midrange is 50.
