Question

Researchers conducted a study to determine whether there were significant differences in graduation between medical students admitted through special programs and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 96% for the medical students admitted through special programs in all medical schools. Complete parts (a) and (b) below. If 13 of the students admitted through special programs are randomly selected, find the probability that at least 12 of them graduated. The probability that at least 12 of the 13 students graduated is. (Round to three decimal places as needed.)

Explanation / Answer

p=0.96

n=13

Binomial distribution used

P( x 12)

=P( x=12)+P( x=13)

=0.3186+0.5882

=0.9068

The required P=0.907    ( three decimals)
