He takes a randomsample of 530 employed adults and finds that 324 of them feel thatbasic mathematical skills are critical or very important to theirjob. Is there sufficient evidence to conclude that the proportionof employed adults who feel basic mathematical skills are criticalor very important to their job has increased at the ? = 0.01 levelof significance?
