A friend of yours tells you that they heard that 65% of all college athletes end up losing a finger or toe in their college athletic career.  You're highly skeptical of this, but your not sure if that percentage is an over exageration or an under exageration.  You survey 101 former student-athletes and find that 60 of them lost a digit during their college athletic career.  Is this enough evidence to conclude that the true percentage of student-athletes that lose a digit during their collegiate career is really different from 65%?
