Question

Which of the statements below is true for the following set of numbers? 20, 15, 50, 85, 75, 60A. The range is 70 and the midrange is 35 B.the range is 70 and the midrange is 50C. The range is 85 and the midrange is 55D.the range and the midrange are equal

Answer 1

B

1) Firstly, we need to orderly write this sequence of numbers:

`15,20,50,60,75,85`

2) Then we need to calculate the Range of this Data Set, by subtracting from the highest values the least one:

`R=85-15=70`

2.2) The Midrange is the average between the Highest Value and the Least value on this Data Set:

`M=(85+15)/(2)=50`

3) Thus the answer is B
