For the recent year, the worth (in billions of dollars) of a sample of the 10 wealthiest people under the age of 60 is shown:
14, 12, 48, 20, 18, 18, 12.6, 10.4, 7.3, 5.3
The worth of a sample of 10 of the wealthiest people age 60 and over is shown:
41.0, 13.7, 10.0, 18.0, 11.3, 7.6, 7, 18, 20, 60
(a) Find the (1) Mean, (2) Median, (3) and the mid-range. Based on the averages, can you conclude that those over 60 years old and over have a higher net worth?
(b) Find the standard deviation and variance and compare both.
