Answer: The required mean is -48.
Step-by-step explanation: We are given to find the mean of the following integers :
-54, -32, -70, -25, -65, -42
We know that
the mean of a set of integers is equal to the sum of the integers divided by the number of integers.
Here, the sum of the integers is given by

and the number of integers is

Therefore, the mean of the given integers is

Thus, the required mean is -48.
