During the Vietnam War a lottery system was instituted to choose males to be drafted into the military. Numbers representing days of the year were supposedly randomly selected; men born on days of the year with low numbers were drafted first; those with high numbers were not drafted. The following shows how many low (1-122), medium (123-244) and high (245-366) numbers were drawn in each quarter of the year: Quarter of the Year Jan. Apr. Jul. Oct. Total Low 21 28 35 38 122 Medium 34 22 29 37 122 High 36 41 28 17 122 Total 91 91 92 92 366 Is there evidence that the numbers drawn are independent of quarter?
