A study compared graduation rates of students admitted through special programs versus regular admissions. It found a 92.7% graduation rate for special program students. The summary calculates probabilities for randomly selecting 12 such students and the likelihood that: at least 11 graduated (0.617), exactly 9 graduated (0.166), at most 9 graduated (0.422), and only 9 graduated (0.166). The results indicate getting 9 graduates would not be unusual.

1. A study was conducted to determine whether there were significant differences between college
students admitted through special programs (such as retention incentive and guaranteed
placement programs) and college students admitted through the regular admissions criteria. It
was found that the graduation rate was 92.7% for the college students admitted through special
programs. If 12 of the students from the special programs are randomly selected, find the
probability that at least 11 of them graduated. prob= If 12 of the students from the special
programs are randomly selected, find the probability that eactly 9 of them graduated. prob=
Would it be unusual to randomly select 12 students from the special programs and get exactly 9
that graduate? no, it is not unusual yes, it is unusual If 12 of the students from the special
programs are randomly selected, find the probability that at most 9 of them graduated. prob=
Would it be unusual to randomly select 12 students from the special programs and get at most 9
that graduate? no, it is not unusual yes, it is unusual Would it be unusual to randomly select 12
students from the special programs and get only 9 that graduate? no, it is not unusual yes, it is
