Answer:
a. 13
b. 76
Explanation:
The computation is shown below:
a. The range of the numbers in the list
First we have to set in a chronological way
72 73 75 76 76 83 85
Now the range is
= 85 - 72
= 13
b. The median of the number of list
Since n = 8
So here the formula is
= n ÷ 2
= 8 ÷ 2
= 4th value
= 76
