A study was conducted to determine whether there were significant differences between medical students admitted through special programs (such as retention incentive and guaranteed placement programs) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 91.5% for the medical students admitted through special programs.

If 10 of the students from the special programs are randomly selected, find the probability that at least 9 of them graduated.

It was found that the graduation rate was 91.5% for the medical students admitted through special programs.

If 10 of the students from the special programs are randomly selected, find the probability that at least 9 of them graduated.
round your answer to 4 decimal places
prob =

=BINOM.DIST(9,10,0.915,FALSE)+BINOM.DIST(10,10,0.915,FALSE)

=0.7934

If 10 of the students from the special programs are randomly selected, find the probability that exactly 7 of them graduated.
round your answer to 4 decimal places
prob =

=BINOM.DIST(7,10,0.915,FALSE)

=0.0396

Would it be unusual to randomly select 10 students from the special programs and get exactly 7 that graduate?

  • yes, it is unusual. The probability of that is very low

If 10 of the students from the special programs are randomly selected, find the probability that at most 7 of them graduated.
round your answer to 4 decimal places
prob =

=BINOM.DIST(7,10,0.915,TRUE)

=0.0468

Would it be unusual to randomly select 10 students from the special programs and get at most 7 that graduate?
