Solution

Calculate the mean of integer
Mean of the integers $= \frac{s u m o f a l l i n t e g e r s}{t o t a l n u m b e r o f i n t e g e r s}$
Mean of the integers $= \frac{(- 54) + (- 32) + (- 70) + (- 25) + (- 65) + (- 42)}{6}$
$= \frac{- 54 - 32 - 70 - 25 - 65 - 42}{6} = \frac{- 288}{6} = - 48$
Hence, the mean of integers is $- 48$ .
