What is the sample proportion?

A study was conducted to determine if there was a difference in the driving ability of students from West University and East University by sending a survey to a sample of 100 students at both universities. Of the 100 sampled from West University, 15 reported they had been involved in a car accident within the past year. Of the 100 randomly sampled students from East University, 12 students reported they had been involved in a car accident within the past year.
