Answer 1

Answer:

Step-by-step explanation:

It is given that the given data set is:

5, 6, 7, 5, 7, 9, 2, 4, 8, and 7.

In order to find the the difference of the greatest and the least number of pins, first arrange the given data set in ascending order, we have

2, 4, 5, 5, 6, 7, 7, 7, 8, 9

Now, we use the range in order to find the difference of the greatest and the least number of the given data set,thus by the definition of the range, we have

$Range=Highest term-lowest term$

$Range=9-2$

$Range=7$

Therefore, Alan use range to learn the difference of the greatest and the least number of pins he knocked down which is equal to 7.

Answer 2

Range....Range is the difference between the lower and upper values.
