Between 2001 and 2002, astrophysicists discovered new irregular moons of Neptune, with diameters (in kilometers) of 31, 33, 36, 37, 43, and 54. [Subsequently, five of the six discoveries were made official.]
a. Find the mean diameter of these six moons.
b. Does it make sense to use this mean as an estimate for a population mean? Explain.
c. Explain why the median would do a better job of reporting what diameter is typical for Neptune's six new irregular moons.
