Answer 2

Find the arithmetic mean for the scores 8, 6, 10, 12, 1, 3, 4, 4.

$\\ \\ \bold{Mean - \frac{total \: number \: of \: observation}{number \: of \: observation}} \\ \\ \bold{Mean = \frac{8 + 6 + 10 + 12 + 1 + 3 + 4 + 4}{8}} \\ \\ = \bold{\frac{48}{8}} \\ \\ \bold{= 6} \\ \\ \bold {Range = maximum \: value - minimum \: value} \\ \\ \bold{= 12 - 1} \\ \\ \bold{= 11 }$
