Combining rasters at different resolutions

I have a question regarding use of the combine tool.

I have two rasters, one at 3x3 resolution and one at 1x1 resolution.

When these rasters are combined using the "Combine" tool in the spatial analyst tool box (not considering arcpy), what method is used to determine the value in the new combined 3x3 raster?  There are no options for choosing an interpolation method for this tool.

There is no mention of this in directly in the tool information.  Does this tool work by choosing the value of the pixel closest to the centroid of the larger pixel or is there an average taken from all pixels intersecting the larger pixel.

Any insight would be appreciated.
