I imported projections for a  shapefile with unknown reference, but it doesn't sit on top of the layer which I imported the coordinate info from. The extend shows two different values! Do I need to change the projection, any suggestion for Massachusetts data? Any solution please? Thanks in advance.

Hi Bahare,

You will need to use the Define Projection tool to define the coordinate system of what the shapefile was created in.  Here is support article that discusses how to find this coordinate system:
