Respuesta :

B

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

[tex]15,20,50,60,75,85[/tex]

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

[tex]R=85-15=70[/tex]

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

[tex]M=\frac{85+15}{2}=50[/tex]

3) Thus the answer is B
