topic: measures of center\nprogress:\nthe movement of the progress bar may be uneven because questions can be worth more or less (including zero) depending on your answer.\nwhich of the statements below is true for the following set of numbers?\n20, 15, 50, 85, 75, 60\nthe range is 70 and the midrange is 35.\nthe range and the midrange are equal.\nthe range is 85 and the midrange is 55.\nthe range is 70 and the midrange is 50.
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.
