Explanation

The mean of the data is the assumed mean plus the mean of the deviations. Mean = 12 + 25 = 37.

AI explanation

Using the assumed mean method, the formula for the actual mean is the assumed mean plus the mean of the deviations. You are given that the assumed mean is 12 and the mean of the deviations is 25. Substitute these values into the formula to get 12 plus 25, which equals 37.
