The deviation of a data point from the mean is calculated by subtracting the mean from the data point. In this case, the mean is 59, and the data point is 43.
To calculate the deviation:
\[ \text{Deviation} = \text{Data Point} - \text{Mean} \] \[ \text{Deviation} = 43 - 59 = -16 \]
So, the deviation of the data point at 43 is \(-16\).
The correct response is \(-16\).
