Answer 1

The range is the change in value. Calculated by subtracting the lowest value from the highest value

The maximum age of the players is 12. The range of the ages of the players is 4, therefore:

`\begin{gathered} 4=12-x \\ x=8 \end{gathered}`

The minumum age is 8

The mode is the number which appears most often in the list

since the mode of the age of the players is shared by 2 different ages, and the minimum, maximum, mode and media are all different ages, we can choose the following ages:

`8,8,9,10,10,11,12`
