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.

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

Medical researchers conducted a study to determine whether treadmill exercise could improve the walking ability of patients suffering from claudication, which is pain caused by insufficient blood flow to the muscles of the legs. A sample of patients walked on the treadmill every day and after six months the mean walking distance was measured. A control group of patients that did not walk on the treadmill were also measured for mean walking distance. The data for each group is as...
