According to Forbes, the average age of millionaires in the US 10 years ago was 62 years old. Since
then, the number of millionaires in the US has grown to over 17 million. One prevalent belief among
economists is that the average age of millionaires today has decreased from the average age of
millionaires 10 years ago. To investigate this belief, a random sample of 50 millionaires from the US was
selected and their ages were recorded. Here are the summary statistics.
