You are interested in understanding your employees and their potential attrition. In order to understand what percentage of employees are likely to leave you anonymously survey 400 randomly chosen employees (out of over 20,000 employees in the company).

In the survey, 117 respondents answered "yes" they are likely to leave in the next year.
