Question

Researchers conducted a study to determine whether there were significant differences in graduation rates between medical students admitted through special programs and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 9292% for the medical students admitted through special programs in all medical schools. Complete parts (a) and (b) below. a. If 1313 of the students admitted through special programs are randomly selected, find the probability that at least 1212 of them graduated. The probability that at least 1212 of the 1313 students graduated is

Explanation / Answer

Given that n = 13

p = 0.92, q = 0.08

Usign binomial distribution

p [x>=12] = p [12] + p [13]

= 13c12 * 0.9212 * 0.081 + 0.9213

= 0.7206
