Question

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 90.2% for the medical students admitted through special programs. Be sure to enter at least 4 digits of accuracy for this problem!
