Blue Embrold.. Pointehaven 200 G. PANDOR A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentve and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 91.9% for the medical students admitted through special programs. A sample of 11 students from the special programs are randomly selected. An event is considered unusual if it has a probability of less than 5%. Round to at least 4 decimal places! a) Compute the probability that at least 10 of them graduated. b) Compute the probability that exactly 8 of them graduated. C) Would it be unusual to randomly select 11 students from the special programs and get exactly 8 that graduate? O no, it is not unusual O yes, it is unusual d) Compute the probability that at most 8 of them graduated. e) Would it be unusual to randomly select 11 students…
