     The data set 'draft' contains average lottery numbers by month for
     the 1970 Draft Lottery. In December of 1969 the U.S. randomly drew
     from the 366 possible birthdays without replacement. The draw
     order of each birhtday determined the order by which men born
     between 1944-1950 (those eligible in the 1970 draft) were drafted.
     For example, a person with a birthday lottery number of 63 was
     drafted fairly early in 1970; a person with number 300 was not
     drafted at all. Sommers (2003, Chance Magazine) looked up deaths
     by age and birthday on the Vietnam Veterans Memorial. Thus, the
     data set has deaths by month as well.
