In the year 2000 there were 34.7M people over the age of 65 out of a total population of 274M. It is estimated that in the year 2050 there will be 78.9M people over age 65 out of a total population of 394M. Are the chances greater in 2000 or 2050 of running into someone over the age of 65? Explain.
I'll save the answer for later. I want you people to answer this. Then I will explain why I overthought it. :)
OH, and don't anyone be all, "Well, Alica, it's a simple statistical problem, see you just do this and this and that's it."
Background info on this class is that it's the fourth week. There is no way a question this easy should be posed at this point. Unless she was giving us a break...hmmmm
