16 In 1970, the U.S. Armed Services instituted a lottery as a random selection process when 19- year old males were drafted into service. Each of the possible 366 possible birth dates was placed in a separate capsule and each capsule was placed in a large plastic drum. Those with the lowest lottery numbers were drafted before others. For example, the May 9th was 176. This meant that there would be 175 groups of males born on other days drafted before those who had been born on May 9th. The scatter plot below shows the median draft eligible number for each month of the year. The line that connects the points is sometimes called a median trace line. Which one of the following statement is TRUE? * Median Trace of Draft Lottery Numbers 240 220- 200- 180- 160 140 120 100 F M. A Median Draft Number to
