Interpolation & Decimation

Hello,
  If a signal is usampled by a factor L & then passed through a filter to
interpolate & now I downsample this signal by N where L>N,(or decimate),
will my resulting signal have an upsampling rate of : L/N ? 
Will there be any change to the statistics of this signal? If my original
signal was gaussian distributed,will the new signal be gaussian
distributed too?
Looking forward for a reply! Thank you.

Regds,

This sounds too much like a homework problem. You should clarify this first
and then expect some reasonable answers. Also - it would be nice if you
wrote what your thoughts are on these questions and let the group correct
you.
