The mean is increased 6 fold.
Explanation:
Recall that the mean is the sum of the values divided by the count of the values:
For the sum of the values, let's say we have two values:
And now let's multiply the values by 6 (keeping in mind that what we do to one side we must do to the other to keep the equation balanced):
And there's our answer - the mean is increased 6 fold.
