Astronomers are interested in understanding the recessional velocity of galaxies – that is, the speed at which they are moving away from us. The accompanying table contains the recessional velocities for a sample of galaxies, measured in km/sec. Negative velocity indicates the galaxy is moving towards us.

  1. Calculate these numerical summaries:
    The mean ____ 418.42 ______
    The standard deviation _____ 381.84 ______
    The median _____ 300 _____
    The interquartile range _____ 630 __________
  2. Construct and properly label a box plot for these data. Also indicate the key features (Five Number Summary) that are present in your box plot. (Hint – you can use the MS Word Draw function to do this.
